Abstract
The effects of strike on national development cannot be over-emphasized. Strikes and lockouts are a form of protest by workers against employers for non-satisfactory management or reward. This paper focuses on the causes and economic effects of strike in Nigeria. In carrying out the research, four hypotheses were generated and tested. Questionnaires were administered to 75 (seventy-five) members of academic staff union of universities (ASUU), Non-Academic Staff Union and the general public. Out of the seventy-five questionnaires distributed, 60 copies were retrieved for analysis. The data analyses revealed that economic difficulties, ecological factors, relative deprivation, government policies and decisions and non-implementation of policies are major causes of strikes in Nigeria. The paper therefore recommends amongst others, that there should be improvement in the relationship between workers and management, prompt response to workers demands, regular payment of workers’ salary and wages. The paper added that government should set up monetary fiscal policies to reduce the galloping inflation and embezzlement of funds; and professions should be regarded as important and equal by government and employers of labour.
