What happened to No Contract-No Work

During the transit strike, defenders of the TWU when asked why the union was striking while other municipal unions did not strike even as negotiations dragged on for years, fell back on one defense – that the TWU had a policy of no contract – no work. Now even at the time, this was a pretty weak argument for so called progressives to make – "tradition requires a strike". But now, as we are in the 5th month of no contact, I’m wondering what happened to no work? Even the anti-Toussaint militants aren’t demanding an immediate strike . Has this important policy gone the way of the token?
