Even the Finance Ministry agrees that an increase in pay and benefits is needed, as quoted in Ha'aretz today: "Talks over the weekend failed to find an agreement, although Finance Ministry officials agreed that employment terms of contract workers need to improve." So what's stopping Netanyahu from signing legislation implementing those much needed increases? If he is so concerned about the economic consequences of a General Strike: "We must bring a solution that will not harm the Israeli economy at a time when there is a global shake-up in all the world's economies," he said. "There is no need to disrupt the lives of Israelis. We must not risk what we have achieved with much work.". He knows how to prevent this "disruption". It's not empty rhetoric that's needed here - but action!
