A union representing contract staff at York University in Toronto say there are no scheduled negotiations this weekend ahead of a strike deadline.

The bargaining team for CUPE 3903 says staff are planning to go on strike on Monday after voting to reject the university's final offer Friday.

The union represents contract faculty members, teaching assistants, graduate assistants, research assistants and part-time librarians and archivists.

The union and school say their positions on a number of issues are too far apart to reach an agreement at this time.

The university says it will remain open during a strike and that classes not impacted by the strike will go on as scheduled.

It says libraries, restaurants, administrative offices and other services will remain open.
