Kenyatta University v Humprey Nyaga Thomas & 8 others
The bottom line
#Kenyatta University workers won conversion from casual to monthly contracts, but the Court of Appeal trimmed their victory: no discrimination finding, no equal terms, overtime limited to three years.
What this practically means
#Executive summary
#Key legal issues
#Whether the University discriminated against the respondents contrary to Article 27 of the Constitution and section 5 of the Employment Act
No discrimination was established; the respondents belonged to a distinct cadre of non-core, impermanent workers, so the differential treatment rested on a reasonable distinction rather than an impermissible ground.
Discrimination requires that the differential treatment be on account of an impermissible ground. The University explained that the respondents, being electricians, plumbers, painters, masons and carpenters engaged in non-core infrastructure work, belonged to a different cadre from core academic staff. The respondents did not seriously challenge this, amounting to a concession. Equality permits differentiation; the trial judge's discrimination finding was inconsistent with her own observation that the respondents were distinct in the nature of their engagement.
Whether the respondents were casual employees or fixed-term contract employees
The evidence supported casual employment despite the University's assertion of fixed-term contracts; the University's own pleadings and the 2018 'formalisation' memo confirmed the casual character of the engagement.
The University's reply to the petition described the engagement as intermittent and informal; its correspondence consistently referred to the respondents as casuals; and the purpose of the 9th July 2018 memo was to issue contracts to 'staff on casual terms'. Tax records showed near-continuous employment with only short breaks, which do not alter the true character of the arrangement.
The scope and effect of section 37 of the Employment Act
Section 37(1) converts casual employment to a monthly-paid term contract with notice protection, and section 37(3) confers statutory terms and conditions; it does not convert the employee into a permanent employee, nor justify an order placing them on terms similar to other employees.
The primary remedy is the deeming in subsection (1), coupled with notice under section 35(1)(c) and statutory entitlements under subsection (3). The wider power under subsection (4) to vary terms exists but must be exercised only where circumstances justify, with reasons. Given the trial judge's own recognition of the respondents' unique tasks, ordering terms similar to other employees went beyond what the section justified.
Whether the nullification of the 9th July 2018 memo could bind persons outside the suit
No. The petition was not a representative suit and no relief in rem was sought or could be granted; the nullification applies only to the respondents.
The University objected that nullifying the memo generally affected thousands of persons not before the court. The Court agreed that the declaration could only operate in personam against the University in favour of the respondents before the court.
The temporal limit on the overtime award
The overtime award is limited to a period not exceeding three years before the petition was filed, in line with section 53 of the Labour Institutions Act and section 74 of the Employment Act.
Section 74 requires employers to keep records, and permits inspection of records for the preceding thirty-six months. The purpose of limitation is that a defendant should not be made to meet a claim it cannot properly defend because of the passage of time in gathering evidence.
Legal principles established
#- Casual employees engaged for long continuous periods are deemed, under section 37(1) of the Employment Act, to be on monthly-paid term contracts protected by notice provisions; but conversion under section 37 does not of itself make the employee permanent.
- Short artificial breaks in an otherwise continuous casual engagement do not defeat conversion under section 37 of the Employment Act.
- A court may only exercise the power under section 37(4) of the Employment Act to vary terms of service and declare terms consistent with the Act where circumstances justify it, and must give reasons for such variation.
- Equality does not connote exact equal treatment; differential treatment grounded on a reasonable distinction in the nature of work is not discrimination.
- Overtime claims in employment disputes are limited, in line with section 53 of the Labour Institutions Act and section 74 of the Employment Act, to a period not exceeding three years before the filing of the claim.
- A declaration in constitutional proceedings binds only the parties before the court unless a decision in rem is sought and is warranted.
