From one of several notes on this subject to members from the Canadian Media Guild -- the CBC labor union -- back in 2014:
'To be absolutely clear – CMG members working for the CBC
are permitted to take part in activities outside the workplace.
Article 12 of the agreement says in part: “Employees shall be free to engage in activities, such as voluntary and/or paid work outside their hours of work….” '
The whole thing can be found at:

The problem is that grievances/arbitrations can take forever and the guy has to make a living. So even if he wins, he probably doesn't.
