Gatineau transit workers have set Thursday as the day for their third in a series of rotating one-day strikes.

The Société de transport de l'Outaouais (STO) has been locked in a labour dispute with Local 591 of the Syndicat uni du transport, the union representing drivers and mechanics, who have been without a contract since Dec. 31, 2014.

To increase pressure on the transit agency during negotiations, the union began rotating strikes earlier this month.

Drivers and mechanics have pledged to strike one day a week until management agrees to arbitration and the labour dispute is resolved.

Union president Felix Gendron announced Tuesday that March 30 would be the next strike date.

The STO has urged commuters to consider alternatives such as carpooling, car-sharing, walking or telecommuting on strike days.

The last strike caused a severe shortage of parking in downtown Ottawa as people decided to drive to work.
