The preparations for the general strike have begun after talks between Histadrut Chairman Ofer Eini and the Treasury budget director reached a deadlock.
The Histadrut is demanding that the State and private sector minimize the employment of outside contractors and hire most of them as full-fledges workers in the civil service, local authorities and large private companies.
A statement issued by the Histadrut details the list of bodies expected to take part in the strike:
"The Treasury people are the only ones responsible for this strike," Eini told Ynet on Sunday morning. "(Prime Minister Benjamin) Netanyahu acted in a responsible manner and we could have reached an understanding with him. There were understandings, which were torpedoed by the Treasury."
Asked why the Histadrut suddenly remembered to take care of the outside contractors problem, 25 years after it began, Eini responded: "Something happened in the summer of 2011. The people won't accept no social justice, and social justice cannot exist in a place where outside contractors are being exploited."
Meanwhile Sunday, Prime Minister Netanyahu called on the Histadrut leaders to find a solution for the outside contractors problem without launching a strike.
"I believe a just and responsible solution can be found for the outside contractors issue," Netanyahu said at the start of the weekly cabinet meeting. Just – because we are all aware of the outside contractors' real distress. Responsible – because we must reach a solution which won't damage Israel's economy at a time when global economies face a serious crisis.
"I believe there is no need to disrupt the life of Israel's citizens and no need to cause heavy damages to the economy. My government and the Histadrut see eye to eye on the welfare of workers in Israel," he said.
Finance Minister Yuval Steinitz addressed the strike threats as well, saying: "I hope this unnecessary strike will be averted. A strike, even one-week long, can cause irreversible damage, while Europe is collapsing.
"The last thing we need right now is a strike and disruptions to the economy. We share a real desire to bolster the weak workers and take care of their conditions, and stop the exploitation.
"We are working on forcing all employers to honor their workers, ensure decent pay and even holiday gifts. There is no reason to keep Israel's citizens hostage."
