The University of Winnipeg Faculty Association voted overwhelmingly in favour of striking on Tuesday and set a strike deadline of Feb. 24 on Wednesday.
Of members who voted, 92 per cent were in favour of strike action, which means the association can now call a strike at any time.
The two parties have been in ongoing negotiations and are expected to begin mediation on Feb. 6.
Hugh Grant, president of the University of Winnipeg Faculty Association, said the U of W isn't well funded. Nevertheless, he said, it needs to make salary increases for professors a priority.
"Our concern is the extent to which the money that the university does have is being drained off into other areas and ignoring the core teaching and research function," he said.
He said U of W faculty members are paid at least 10 per cent less than professors at comparable universities.
"We certainly have no expectations of achieving the same overall rates of pay that the University of Manitoba enjoys right now," he said. "But we want some movement at least and commitment towards closing the gap in salary."
In October, the University of Manitoba’s faculty association voted in favour of striking, but ultimately came to an agreement with the university, averting an actual strike just before a faculty association imposed deadline.
The U of W faculty last threatened to strike in 2011, after they had been working without a contract for almost a year.
