Brief Summary

Labour Law — Employment Conditions — Unilateral Change in Working Hours — Applicants, security officers, contesting the First Respondent's unilateral reduction of their working hours from 60 to 48 per week following the implementation of a Sectoral Determination — Court finding that the reduction constituted an unlawful variation of the Applicants' conditions of employment, as no agreement was reached to alter the existing terms — Respondents' reliance on the Sectoral Determination and employment contract clauses deemed insufficient to justify the unilateral change.

JAMMY AJ
1. The Applicants in this matter came before this Court pursuant to an Order  
of Court dated 16 th November 2001, the material provision of which reads  

“The matter is referred to oral evidence on whether the employees, who  
are Applicants, have separately or otherwise entered into an agreement  
with Magnum prior to 6 March 2001 which entitles them to work a specified

number of hours per week.”
2. The Applicants had applied as a matter of urgency for an Order which, as  
amended   subsequent   to   the   Order   of   Court   above   referred   to,   read   as  
follows –
“1 The First  Respondent  is  ordered  to restore the terms  and conditions of  
employment of the Second and Further Applicants that pertained prior to  
20 March 2001;
2. The First Respondent is ordered to roster the individual Applicants on five  
12   hour   shifts   per   week   unless   otherwise   agreed   with   the   individual  
Applicants and for as long as this is not precluded by law;
ALTERNATIVELY
The   First   Respondent   is   ordered   to   roster   the   individual  
Applicants to work at least 55 hours per week unless otherwise agreed  
with the individual Applicants and for as long as this is not precluded by  
law;
ALTERNATIVELY
The First Respondent is ordered to roster the individual Applicants to work  
at   least   50  hours  per   week  unless   otherwise   agreed   with  the   individual  
Applicants and for as long as this is not precluded by law.
3. The First Respondent is ordered to compensate the individual Applicants  
by  paying to  them  the  difference  between  the  amount  they  would  have  
earned between 20   March 2001 and the date of Order had they worked 60

actual hours per week, alternatively 55 hours per week, alternatively 50  
hours   per   week   during   that   period   and   the   amount   in   fact   paid   to   the  
individual Applicants during that period”.
3. The First Respondent provides contract guarding services to its customers  
and employs the individual Applicants as security officers.  Between April  
1996   and   March   2000,   the   terms   and   conditions   of   employment   of   the  
individual   Applicants   were   regulated   by   a   labour   order   which   provided  
weekly   working   hours,   for   the   grade   of   employment   applicable   to   the  
Applicants, of a maximum of 72, 60 hours of which were “ordinary” hours  
of   work   and   12   hours   were   overtime.     As   was   a   norm   in   the   security  
industry at the time, the 72 hour week comprised six 12 hour shifts per  
week.
4. On   6   March   2000   Sectoral   Determination   3,   issued   by   the   Minister   of  
Labour in terms of the Basic Conditions of Employment Act 1997, became  
effective and provided that, for the twelve month period commencing on  
that date, employers and security officers were permitted to agree to work  
a total of 65 hours per week, of which 10 would be overtime – in other  
words, a working week comprising 55 ordinary and 10 overtime hours.
5. A further provision of the Sectoral Determination however was that:
“(a) With   effect   from   one   year   after   the   implementation   of   this  
Determination the second transitional phase of schedule three of the Basic  
Conditions  of Employment Act  No 75  of 1997 as  amended,  comes  into  
effect, from which time the maximum permissible weekly hours of work for  
a Category B security officer will be reduced to fifty;
(b) With   effect   from   two   years   after   the   implementation   of   this

Determination the third transitional phase of schedule three of the Basic  
Conditions of Employment Act, Act No 75 of 1997 as amended, comes into  
effect from which time the maximum permissible weekly hours of work for  
any security officer will be reduced to 45 and the terms “Category A” and  
“Category B” will be discontinued.
6. In   essence   therefore,   for   the   twelve   month   period   from   6   March   2001  
employers   and   security   officers   were   in   terms   of   the   Sectoral  
Determination permitted to agree to work a total of 60 hours per week, of  
which 10 would be overtime hours.
7. Immediately  prior  to  March 2001  and  pursuant  to  the  first  phase  of  the  
Sectoral Determination, the working hours of the individual Applicants, as  
agreed with the First Respondent, were 60 per week.  In the context of the  
Sectoral Determination, which, as indicated, permitted a maximum of 55  
ordinary hours, 5 of those 60 hours per week constituted overtime.
8. During February 2001 the First Respondent issued a notice to all members  
of its staff of which the following provisions were relevant to this dispute:
“Reduction of Working Hours
All Staff are reminded that the Private Security Industry hours of work are to be  
reduced from 55 to 50 hours per week as from 6 March 2001.
The   reduction   is   in   accordance   with   the   Security   Industry   Basic   Conditions   of  
Employment Act No 75 of 1997.
However   it   is   not   practical   to   have   a   50   hour   week   in   certain   Sectors   of   our  
business.  The Trade Unions are consulted over the practical 48 hour week.  This

could mean that you will be required to work 4 days of 12 hour shifts and 3 days  
off, with effect from 6 th  March 2001”.
9. The   express   terms   of   the   individual   Applicants’   employment   were  
embodied in an employment contract concluded by each of them with the  
First Respondent at the time of their engagement.  Two specific clauses of  
that contract bear reference in this dispute.  They are the following –
“9 Other   conditions   of   service   related   to   rate   of   pay,   work   hours,   leave  
entitlement is governed and regulated by Gazette which is published by  
the   relevant   minister.     These   conditions   will   be   covered   and   explained  
during induction and will change from time to time in accordance with the  
Government Gazette as and when published.
10 Your employment is furthermore conditional to:

10.5 placing my services at the disposal of the company in such a manner  
that the company can achieve its business objectives”.
10. At   the   time   of   the   staff   directive   referred   to   above,   the   prevailing  
agreement between the parties was, as I have stated, that the individual  
Applicants would work 60 hours per week comprising 55 ordinary hours  
and 5  hours  overtime.     The  directive  was  in  consequence  rejected,  the  
Applicants contending that they had at no stage agreed to a reduction in  
their   actual   working   hours.     Their   contention   was   accordingly   that  
notwithstanding   the   provisions  of   the  Sectoral   Determination  requiring   a  
formal   reduction   in   the   maximum   ordinary   hours   from   55   to   50,   the  
prevailing 60 hour agreement would remain of force and effect, it being an

implied term thereof, as pleaded by them that –
“When the weekly maximum permissible ordinary hours of work prescribed  
in the Sectoral Determination were reduced, the number of ordinary hours  
to   be   worked   each   week   would   reduce   to   the   new   maximum   and   the  
number   of   overtime   hours   required   to   be   worked   would   increase  
correspondingly, provided that the total ordinary and overtime hours would  
not exceed the maxima prescribed in the Sectoral Determination”.
11. The proposed reduction in ordinary working hours to 48 per week would,  
the Applicants therefore contend, constitute a unilateral and unlawful act  
on the part of the First Respondent.  The Respondents on their part deny  
the existence of the alleged implied term relied upon by the Applicants, the  
effect of which would be that the 60 hour agreement would remain in force  
after  6  March  2001  and  be adjusted  to  provide for  50  ordinary  working  
hours   and   10   overtime   hours   instead   of   the   55   ordinary   hours   and   5  
overtime hours prevailing prior to that date.
12. Commendably   comprehensive   argument   was   presented   by   the   legal  
representatives   of   the   parties,   traversing   in   detail   the   horological  
ramifications of the employment contract, the Sectoral Determinations and  
undisputed agreements between the parties, as well as the legal principles  
applicable where contracts are alleged to embody terms which are implied  
rather than expressed.   It is unnecessary, in my view, for me to review  
those submissions in detail.   The crisp issue, as submitted by Advocate  
Reynecke,   representing   the   Respondents,   is   whether   there   was   in  
existence and enforceable and implied term in  the conditions  governing  
the Applicants’ employment which would result in the maintenance of a 60  
hour   working   week   as   agreed   between   the   parties,   the   ordinary   and

overtime   components   of   which   would   be   subject   to   adjustment   in  
compliance with Sectoral Determinations necessitating the alteration of the  
ratio   of   the   one   to   the   other.     Thus   the   pre­March   2001   agreement  
providing for 55 ordinary hours and 5 overtime hours would, of necessity  
from   that   date   be   reconstituted   so   as   to   establish   a   maximum   of   50  
ordinary hours and, to maintain the aggregate, 10 hours of overtime.
13. In essence therefore, the individual applicants contend that the unilateral  
reduction by the First Respondent of their total working hours from 60 to  
48   per   week   constituted   an   unlawful   variation   of   their   conditions   of  
employment which, whilst complying with the maximum ordinary hours of  
work which came into effect from 6 March 2001, would radically reduce the  
remuneration earned by them, their hourly wage rate remaining unaltered  
whilst   they   would   now   work   2   ordinary   hours   less   than   the   prescribed  
maximum, with no overtime whatsoever.
14. The   alleged   existence   of   such   an   implied   term   in   the   conditions   of  
employment of the individual Applicants, is rejected by the Respondents.  
The working hour scenario at any given time, it is contended, is governed  
by   clause   9   and,   less   emphatically,   clause   10.5   of   the   individual  
Applicants’ employment contracts.
15. The practical necessity, as a norm in the security industry, for employers to  
operate on a 12 hour shift basis, and the cost implications associated with  
overtime work, were analysed in considerable detail by Mr   A  W  Botes who,  
at all material times, was a member of the executive management of the  
Second  Respondent.   His  testimony on behalf  of the Respondents  was  
endorsed in that context by Mr   J  A  Bezuidenhout who is the manager of  
the Johannesburg Central Branch of the First Respondent and who dealt

the Johannesburg Central Branch of the First Respondent and who dealt  
further with certain variations to that established logistical principle where

the identity and the nature of business of the client concerned dictated this.
16. The reason why, following the promulgation of the Sectoral Determination,  
the First Respondent adopted a 4 day, 12 hour, shift system aggregating  
48 hours per week, said Mr   Bezuidenhout, was because the maintenance  
of a 50 ordinary hour plus 10 overtime hour week would be impossible to  
administer, creating instability at the site  being serviced, the  removal  of  
guards in mid­shift and the incurring of untenable transport and overtime  
costs in an industry where the overall cost of labour is already some 70%  
of turnover.  The implementation of a “50 plus 10” system would increase  
the   Respondents’   wage   cost   by  some   8%,  a  factor   which   could  not   be  
passed   on   to   clients   of   the   company   in   the   context   of   the   intensely  
competitive nature of the industry.
17. The   fact   that,   by   reducing   the   actual   working   hours   applicable   to   the  
Applicants   to   48   per   week,   the   First   Respondent   unilaterally   effected   a  
change to their agreed conditions of employment, is not open to debate.  
No   provision   was   made   in   the   60   hour   agreement   to   cater   for   that  
possibility.     In   the   ordinary   course   a   contract   between   two   parties   is   a  
consensual agreement, capable of amendment only by further agreement  
between   them,   unless   its   own   terms,   or   circumstances   beyond   their  
individual control, necessitates this.
18. The Respondents’ case in essence, is that both those factors exist in the  
present instance.  The Sectoral Determination in question prescribed a 50  
hour   working   week   for   security   officers   in   the   category   governing   the  
employment of the individual Applicants.   That was a matter beyond the  
control of the Respondents.  Secondly, such an eventuality is envisaged in  
clause   9   of   their   employment   contracts   which   expressly   provides   that

clause   9   of   their   employment   contracts   which   expressly   provides   that  
specified conditions of service, including “work hours”, are “governed and

regulated by Gazette” and will “change from time to time in accordance  
with the Government Gazette as and when published”.
19. Clause 10.5 of the contract providing for the placement of the employees’  
services   “at   the   disposal   of   the   company   in   such   a   manner   that   the  
company   can   achieve   its   business   objectives”   was   not,   correctly   in   my  
view, advanced by the First Respondent as a further factor justifying the  
unilateral   change   to   working   hours   effected   by   it.     Mr   C  Todd,   who  
appeared for the Applicants, submitted, and I agree, that regulation of the  
“manner” in which services are to be performed relates, in the context, to  
the   conduct   of   the   employees   rendering   those   services   and   not   to   the  
basic conditions of their employment.  For that reason, I do not propose to  
deal further with that specific line of argument.
20. With   regard  to  clause   9,  the  Applicants  argue   that   the  reference   to  the  
regulation,   inter alia,   of hours of work by “Gazette which is published by  
the Minister”, quite apart from the fact that it is clearly intended to relate  to  
ordinary hours, cannot preclude agreement between the parties as to the  
actual hours to be worked by the employees concerned.  There is nothing  
either   in   the   Sectoral   Determination   or   in   that   specific   term   of   the  
employment   contract,   which   precludes   agreement   as   to   the   number   of  
overtime hours which employees may work in excess of the ordinary hours  
prescribed, subject of course to any applicable statutory limitation in that  
regard.
21. I am in agreement with that submission, more particularly when regard is  
had to paragraph 8 of the Sectoral Determination of 6   March 2000 which  
makes express provision for overtime work.  It reads as follows:

“Limitation   of   overtime:     An   employer   shall   not   require   or   permit   an  
employee   to   work   overtime   otherwise   than   in   terms   of   an   agreement  
concluded by the employer with the employee and such overtime shall not  
exceed, in the case of –
(a) a casual employee, 3 hours on any day;
(b) any other class of employee, 10 hours in any week.”
22. On   that   basis,   it   will   be   evident   that   the   pre­March   2001   agreement  
between the parties, duly adjusted to establish a “50/10” working week,  
would not, if maintained, fall foul in any respect of the provisions of the  
Determination which came into effect on that date. 
23. Much of the substance of the argument submitted by both parties in the  
course of this hearing related to the principles governing, and the factual  
existence of, an implied term in the Applicants’ conditions of employment  
which would have entitled them to continue working overtime regardless of  
various Sectoral  Determinations.   It  does not  seem to  me however that  
this,   in   the   circumstances   which   I   have   reviewed,   is   a   material  
consideration.  I have already made mention of the circumstances in which  
an agreement consensually concluded between contracting parties may be  
amended or varied unilaterally by either of them.  For the reasons which I  
have stated, this does not seem to me to be such a case.  The existence  
of the “60 hour” agreement is not in dispute insofar as it was applicable  
immediately   prior   to   March   2001.     There   is   nothing   in   the   Sectoral  
Determination which renders that agreement ineffective when the ratio of  
ordinary to overtime hours is adjusted to comply with the Determination  
whilst   maintaining   the   actual   working   hours   for   which   that   agreement  
provides.  The necessity to redefine that ratio is one envisaged by clause 9  
of   the   employment   contract.     The   unilateral   reduction   in   actual  working

hours effected by the First Respondent, is not.
24. I   conclude   therefore   that   the   First   Respondent   was   not   entitled,   on   the  
basis of any provision of the contracts of employment of the Applicants,  
unilaterally to change or vary the actual hours to be worked by them after  
6  March   2001,   as   opposed   to   the   maximum   ordinary   hours   forming   a  
component   thereof,   which,   as   I   have   stated,   then   became   legislatively  
prescribed.     Unless   amended   consensually   in   proper   consultation,   the  
actual hours which the individual Applicants were entitled to continue to  
work remained at 60 and if, of necessity in the light of the Determination,  
the overtime component thereof was increased, that issue could not justify  
unilateral   interference   by   the   First   Respondent,   whatever   the   perceived  
commercial necessity for it to do so may have been.  That, as I have said,  
was a matter for consultation and negotiation in the ordinary course of fair  
labour practice.
25. For these reasons, and in the context of the amended notice of
application of record in this matter, the order that I make is the
following:
25.1 the First Respondent is ordered to roster the individual Applicants on five  
12   hour   shifts   per   week,   unless   otherwise   agreed   with   the   individual  
Applicants and for as long as this is not precluded by law;
25.2 the actual working week of 60 hours thereby constituted is to be defined as  
to   the   respective   ordinary   and   overtime   components   thereof,   so   as   to  
comply   with   the   prevailing   Sectoral   Determination(s)   for   the   private  
security sector;
25.3 the First Respondent is ordered to compensate the individual Applicants

by  paying to  them  the  difference  between  the  amount  they  would  have  
earned   between   20   March   2001   and   the   date   of   this   Order   had   they  
worked 60 hours per week, comprising 50 ordinary and 10 overtime hours,  
and the amount in fact paid to the individual Applicants during that period; 
25.4 there is no order as to costs
