The Nigeria Labour Congress has given banks which recently sacked workers a 14-day ultimatum to recall them or face a nationwide industrial action.
Six banks recently sacked workers for various reasons.
The position of the NLC was contained in a letter to the banks.
It was signed by the Deputy General Secretary, Chris Uyot, on behalf of the President, Ayuba Wabba.
The NLC said it issued the letter based on the information by the National Union of Banks, Insurance and Financial Institutions Employees that the banks embarked on the arbitrary mass sacking of workers without adherence to labour laws.
The affected banks are Fidelity Bank, Diamond Bank, First City Monument Bank, First Bank, Ecobank and Skye Bank.
The letter by Uyot said: “I have been directed to notify you that we have been informed by our affiliate union, the National Union of Banks, Insurance and Financial Institutions Employees that your bank has arbitrarily sacked a large number of workers contrary to laid down procedures and the country’s extant labour laws.
“In addition, you have also resisted unionisation of workers in your bank despite spirited efforts by the union to amicably engage you in the process.
“By this letter, we are giving your bank fourteen days ultimatum commencing from Thursday 16th June, 2016 to immediately recall all workers so sacked and allow unionisation of workers in the bank or face industrial action, which may include closure of your banks and all its outlets nationwide.
“While hoping our request meets your kind consideration, please, accept our goodwill and best regards.”
