York University and CUPE 3903, representing Teaching Assistants, Contract Course Instructors and some Research Assistants, are presently engaged in collective bargaining.   On Thursday February 22nd, the union will be in a legal strike position and it will also be legal for the University to "lock-out" CUPE 3903's members.   There are a number of bargaining sessions scheduled between now and then. It is also worth remembering that in the majority of cases, collective bargaining leads to an agreement without a strike or lock-out.   To stay up to date on this situation please see York University's official website for labour negotiations   and the CUPE 3903 website.
