Graduate student/TA strike at U of Toronto (MOVING TO FRONT FROM YESTERDAY)

This has been going on about a month, I've only recently caught up on it.  This is a good place to start.  (Thanks to Benj Hellie for the pointer.)

ADDENDUM:  Grad students at York University, Toronto are also striking..

UPDATE:  Several readers sent the news that the strike is over, with an agreement to binding arbitration on the underlying issues.
