Chaos may break out across airports in the country as aviation unions vowed on Sunday to begin a two-day warning strike on Monday. The development could leave many air passengers stranded in Lagos, Abuja, and other airports in the country. Domestic and international airlines are likely to be forced to cancel their flights as aviation workers down tools in protest against what they say is the government’s failure to address their concerns regarding National Minimum Wage Consequential Adjustment and working conditions. Union leaders said they were left with no choice but to take drastic action to force the Federal Government to implement earlier agreements reached on minimum wage and workers’ general welfare. Last week, aviation workers issued a two-day warning strike notice signed by the secretaries general of five unions stating that if the warning strike, scheduled to commence on April 17 failed, an indefinite strike would be embarked upon. The unions threatened to withdraw their services over the refusal of the Federal Government to release the reviewed condition of service negotiated over seven years ago.
