Thank you for contacting us. The option available to you will depend on whether or not you have an Employment Contract in place which states this entitlement or if it is contained in any Staff Handbook or policy document. From the perspective of current Nigerian Labor Law, there is no law that mandates that payments must be made to employees based on the structure you have outlined.
The issue will depend on whether or not you were promised such arrangement before you joined the company and therefore joined as a result, or whether during the course of your employment this was promised by conduct and therefore a new contract was created. Please note that these are technical legal situations and terms and therefore you need to speak to a lawyer directly to advise you. You should consider requesting a paid consultation with a lawyer here (either professional or premium) – https://lawpadi.com/consultation-packages/
