Workers and trade unions in the central Bosnian city of Zenica marked International Workers’ Day with protests and calls for urgent action to prevent the collapse of the local steel industry, warning that thousands of jobs are at risk.

The demonstration, organised by the Metalworkers’ Union of the Federation of Bosnia and Herzegovina, drew workers from multiple sectors after production at the Nova Željezara Zenica plant was halted, leaving its future uncertain.

The company faces mounting debts to state-linked firms, including energy providers and railways, highlighting what officials described as a lack of a viable business plan under current management.

Union leaders said the shutdown was unacceptable, stressing the plant’s long-standing role in the economy. Over two decades, workers produced millions of tonnes of steel and generated significant tax revenues, they said.

At a public forum in Zenica, Prime Minister Nermin Nikšić said the government had exhausted options to support the plant’s current owners and was now considering regaining control to prevent bankruptcy, N1 reported.

A court hearing scheduled for June 25 could determine whether the company enters liquidation. Nikšić said authorities were prepared to intervene to safeguard jobs and stabilise operations, potentially compensating investors as part of an exit deal.

Trade unions backed the prospect of state intervention, arguing the plant retains strong industrial potential and a skilled workforce that should not be lost.

At the rally, union representatives criticised company leadership and warned that workers would continue protests if no solution is found. Supporters, including employees from the public broadcaster BHRT, joined in solidarity, according to N1.

Officials said the May Day mobilisation marked the start of a broader campaign to preserve one of Bosnia’s key industrial assets.
