Unions asked the president to send the law back to parliament, as their proposed amendments had not been considered.
The president will mediate on January 3 a meeting between unions and the government to discuss unions’ proposals to amend the state budget law, union leader Bogdan Hossu said.
"The president promised to address the issue. He took no official position regarding the law, which he only received yesterday. Under the constitution he has 20 days to analyze the law," Hossu added.
The press was not allowed to participate at the meeting between union leaders and the president.
Unions last week sent the president an open letter asking him to send the state budget law back to parliament, as their proposed amendments had not been considered.
Unions said the approved law lays the ground for a deeply antisocial policy, with dramatic medium and long-term effects.
The Romanian Parliament last week approved the state and social insurance budgets, with the bulk of the funds going to education, health, agriculture and infrastructure.
