The SFM strike committee was summoned to an urgent meeting on Wednesday in a bid to avoid more strike action.
“It will be the beginning of negotiations to unravel the conflict,” said Union reps.
Last week, railway service workers downed tools in defence of a public mobility model and demanded that the Palma tram be managed by SFM and not by a private company.
They also called for European Next Generation funds to be allocated to public mobility projects.
If the two sides are unable to cut a deal the strike action will continue on Thursday.
