The appellant, an international NGO providing medical humanitarian services in Zimbabwe, employed the 12 respondents as guards (some as security guard/gardeners) on fixed-term contracts for various periods between 2008 and 2011. The contracts were renewed from time to time during this period. Due to funding challenges, the appellant did not renew the respondents' contracts beyond 2011. The contracts expressly provided that they would terminate automatically at the expiration of the fixed period and that the employer did not guarantee employment beyond the contract period. When the contracts expired, the appellant sent letters confirming non-renewal but stated it would consider the respondents for interviews should any need arise in the future. The appellant subsequently obtained funding for projects in Mbare, Gutu and Chikomba requiring guards and gardeners from those specific communities. The respondents were invited for interviews for these positions but were unsuccessful. Twelve other people from the local communities where the projects would operate were engaged instead. The respondents claimed unfair dismissal, alleging they had a legitimate expectation of re-engagement under section 12B(3)(b) of the Labour Act.
