According to Actualic, UTJ has offered an ultimatum to the Prime Minister - if he does not resolve the Shabbos work crisis, they will begin voting against the coalition.

Let's not forget that Litzman issued an ultimatum last week threatening to quit the coalition if work would be done. Work had been done and he did not quit.

Basically they are threatening with an ultimatum and if their demands are not met they'll issue another ultimatum. It reminds me of the Robin Williams skit about British police that only carry nightsticks and not guns - when they approach a criminal they shout at him - stop, or I'll say stop again! UTJ is telling the Prime Minister - stop, or I'll say stop again!
