In Osogbo, Osun, the workers called for improved welfare package and prompt payment of salaries.
A cross section of public and private workers told NAN in Osogbo that their current monthly emoluments hardly took them home.
They said that only attractive salary, good working condition, training and retraining of workers could guarantee enhanced productivity.
Alhaji Saka Adesiyan, the Osun NLC Chairman, called for a review of the salary structure of workers in both public and private sectors so as to meet the present economic situation in the country.
Adesiyan said that if there was an increased in the workers’ salaries, it would enhance productivity as well as improve the standard of living of workers.
He said better salary structure as well as good work environment would go a long way in assisting workers to meet their responsibilities.
Mrs Sherifat Balogun, a civil servant, said government must ensure prompt payment of salaries and better working condition for workers.
On his part, Mr Oladele Adetunji, TUC Chairman in the state, criticised casualisation of workers in some government establishments and the private sector.
Adetunji said the union would continue to struggle for better working conditions for employees.
He also said that the union would resist attempts by government or private organisations in preventing their employees from unionism.
The NLC Chairman, Mr Sulaiman Adamu, made the call in his speech at the 2014 May Day celebration in Dutse.
“Due to the insecurity ravaging the country, especially the North, we call on the Federal Government and other parties involved to embrace dialogue in order to bring lasting solution.
“They should consider the lives and property of the people above their interests so as to allow peace to reign,’’ Adamu said.
The chairman described the performance of the state government as “remarkable”, saying that it had created conducive working environment for the civil servants.
Adamu, however, urged the government to employ more youths in the state so as to fill the vacuum created by retirement and death of civil servants. (NAN)
