Union president Peter McInnis said Sunday evening in an email that faculty will report for daily strike duty beginning at 7:30 a.m. Monday.
McInnis says he feels the university administration is unlikely to modify its position until a strike has started.
The union says it can't accept the latest contract offer from the school because the raises on the table are well below the cost-of-living.
University president Sean Riley has released a statement saying progress has been made on many issues but the university believes the union's demands are not reasonable.
The St. Francis Xavier Association of University Teachers represents more than 400 members who teach and do research.
