The meeting between Histadrut Chairman Ofer Eini and Prime Minister Binyamin Netanyahu ended with no results on Wednesday.
Manufacturers Association president Shraga Brosh and Union of Local Authorities chairman Shlomo Bohbot also participated in the meeting.
Netanyahu presented "no concrete actions" for the minimum wage and easing the various taxes, the Histradrut said.
Eini, Brosh and Bohbot plan a joint meeting later Wednesday. They will be joined by National Union of Israeli Students chairman Itzik Shmuli.
The Histadrut may declare a general labor dispute Thursday, which will allow it to launch a general strike after the mandatory two-week cooling off period.
