Montreal's white collar workers are in the middle of five weeks of rotating strikes.
On Thursday employees at the Montreal courthouse, and those with legal matters, walked off the job.
They are scheduled to return to work at noon.
White collar employees from Villeray-St. Michel-Park Extension are also on strike, as are those in Rosemont-La Petite Patrie.
On Friday white collar workers with the Montreal Fire department and the boroughs of Lachine and LaSalle will be on strike.
The city's 8,000 white collar workers have been without a contract for four years.
