Halifax Metro Transit may be stopping it services if the employee union and the management do not reach an agreement within the next three days.

Rick Clarke, president of the Nova Scotia Federation of Labour says he was shocked that the city asked for a conciliator to come to the bargaining table just two weeks after it asked the union to make more than 250 concessions.

Clarke said "it's totally undermining the union to the extend that you would have to question if they are trying to break the union."

Amalgamated Transit Union Vice President, Shane O'Leary, says he is confident the union can reach a deal with the city.

If Metro Transit does strike, more than 95-thousand people could be looking for ways to get around the city.
