TORONTO - Teaching assistants and contract faculty at York University have voted 86 per cent in favour of giving their union a strike mandate.

Key issues include job security, tuition fees, workplace equity and higher compensation for graduate students.

The strike mandate doesn't mean instructors and teaching assistants will necessarily go on strike.

The vote gives the union the ability to walk off the job with 72 hours' notice if they cannot come to an agreement with the school.

York has full and part-time graduate and undergraduate degree programs for over 50,000 students in 11 faculties.

Earlier this month, professors and librarians at the University of Windsor ended a 17-day strike.
