There was heavy security presence at the Kaduna Township Stadium on Wednesday as security operatives thoroughly frisked workers who converged on the stadium for the May Day celebration.
Security operatives, who carried out the search operations, comprised officers of the Nigerian Army, police, Civil Defence Corps and the State Security Services.
Elsewhere in the state, security was also tight as armed security agents, mainly members of the Operation Yaki Squad, manned the major cities and trouble spots in the state.
However, the state Nigeria Labour Congress Chairman Adamu Ango, who spoke at a rally in the stadium, urged the state government to stop the casualisation of workers in the state.
According to him, many people have been working in the state for over 18 years now as casual workers.
Appealing to the state government to regularise the appointment of the casual workers, particularly those with the state Forest Management Project and state Environmental Protection Agency, Adamu said the paltry N5, 000 paid each of them every month was unrealistic.
He also urged the state government to settle the arrears of the N18, 000 minimum wages for local government workers without further delay.
He said, "There is the need to find a lasting solution to the challenges associated with the payment of salaries and allowances to local government employees. Even though there is a degree of stability in that direction, the precarious nature of the issue is still a source of concern to labour.
"I wish to remind the governor that workers at the local government level have yet to get their N18, 000 minimum wage arrears."
Meanwhile, the state deputy governor, Ambassador Nuhu Bajoga, who represented Governor Ramallan Yero, said the state placed priority on the welfare of workers.
