PETER WAMBUGU KARIUKI AND 16 OTHERS V KENYA AGRICULTURAL RESEARCH INSTITUTE [2013] KEELRC 373 (KLR)
The bottom line
#Kenya's Industrial Court ruled that long-serving 'casual' workers at KARI were actually permanent employees and awarded them compensation for unfair termination.
What this practically means
#Executive summary
#Key legal issues
#Res judicata / abuse of process
The petition was not barred by res judicata or abuse of process because cause No. 1303 of 2010 was decided by the Industrial Court sitting as a tribunal, which lacked jurisdiction to enforce fundamental rights and freedoms.
The tribunal's award predated the Industrial Court Act, 2011 and the court as a superior court of record. The constitutional question of fundamental rights was substantive, not a mere re-clothing of the earlier claim, and could be litigated before the constitutionally prescribed forum. The doctrine of justiciability pointed to the superior court of record as the correct forum, so the earlier award did not bar the petition.
Whether the petitioners' rights were breached
The petitioners were never casual employees; their continuous service of more than three months converted them to permanent terms, and the respondent's unilateral treatment of their service as terminated breached Article 41(1) and Article 28.
Under section 2 of the Employment Act a casual employee works not longer than twenty-four hours at a time; the petitioners served for years without break. The respondent failed to discharge its burden under section 10(7) to prove terms absent written contracts, failed to comply with sections 9(1) and 41, and its conduct amounted to constructive termination violating the petitioners' dignity.
Remedies
Petitioners entitled to one month's wages in lieu of notice and six months' gross salary for unfair constructive termination, plus costs and certificates of service; other heads of relief refused for lack of evidential support.
The court modified the prayers: wages were agreed at all material times, one month in lieu of notice was reasonable, and six months' gross salary was fair compensation for the constructive termination given the short-term contracts crystallized into permanent employment. No evidence supported overtime, house allowance or other compensatory reliefs, and service pay was unjustified given NSSF membership.
Legal principles established
#- Continuous service beyond three months converts a casual employee to permanent terms under section 37 of the Employment Act, 2007; casual employment is a question of fact, not of label.
- An employer subjects an employee to unfair labour practices under Article 41(1) where, by omission or action, it fails to uphold statutory protections of the employee.
- Employer conduct that undermines the high trust, confidence and cooperation implied in every employment contract amounts to constructive termination.
- The Industrial Court, as a superior court of record under the 2010 Constitution and the Industrial Court Act, 2011, is the primary and authoritative forum for enforcement of fundamental rights in employment and labour disputes.
