A tentative deal has been reached between the Globe and Mail and its unionized employees, averting a work stoppage at the newspaper in the final hour of negotiations.

Unifor — which represents journalists, ad sales people and administrative staff — says details of the agreement would not be provided until after it's ratified by union members.

The deal, reached with the help of a mediator, avoids a work stoppage by the union which had set a 4 p.m. ET strike deadline on Wednesday.

"We have reached a tentative deal which the bargaining team unanimously recommends," said Howard Law, director of the media sector at Unifor on Twitter .

"The strike deadline is suspended until further notice."

Law said the union hopes to hold a ratification vote on Thursday for the 374 Globe employees covered by the agreement.

A spokesman for the Globe and Mail did not immediately respond to requests for comment.

Last week, a day after the previous contract expired, workers at the Globe backed a recommendation by the bargaining committee and voted 92.3 per cent in favour of rejecting the offer that was on the table at the time.

Unifor Local 87-M had said that offer contained weakened job security language and cut the base pay for some advertising sales representatives.

The union also said it contained a requirement that editorial staff — except for reporters — work on advertorial copy.
