Under the Labour Act Cap L1 LFN 2004, the maximum number of ordinary working hours per day for an adult worker, beyond which overtime rates must apply, is:

Section 13 of the Labour Act Cap L1 LFN 2004 stipulates that the normal working hours for an adult worker shall not exceed 8 hours per day or 40 hours per week. Any work performed beyond these limits qualifies as overtime and must be compensated at a rate not less than 1.25 times the normal hourly rate. This provision is fundamental to understanding statutory employment conditions in Nigeria.
