Do rad techs in Canada or Europe have unions?
It has been a few years, but the RP's in Canada were union. They didn't have actual RP Tchnicians as we think of them until recently. The "Health Physics" Techs. were union too. There were about three of them on the eight-unit site. They didn't do job coverage or surveys.
Operators did routine surveys.
HPT's did highly technical stuff like shipping of high-level waste, calibrating sources, etc.
Instruments were calibrated and maintained by electricians and instrument techs.
Decon was done by "Civil Maintenance" who also cleaned the toilets, took out the trash, cleaned the intake screens, etc.
Anyone who had a yellow or green square on his TLD did his own surveys & job coverage. The "techs" wouldn't even ask you why you were there if you had your own meter. If you weren't on the crew they were covering, you were none of their business.
All these people belonged to the Power Workers' Union if they were "house" or the building trades unions if they were contractors.
Job coverage and job surveys were done by "Green Men" who were people of all trades who were trained in RP procedures. If Boilermakers, Electricians, Millwrights, and Pipefitters were all working in one area, they might have had one Green Man for each trade. On large projects, this was handled by clumping all the green men from various trades into a single RP department that was similar to ours. These people (except the Americans) were members of their respective unions and were paid the scale for their individual trades at the foreman's rate. (I once worked there as a contractor removing broken fuel pencils from the pool. The "techs" who covered me would have been union Millwrights - except that I was self-monitor qualified and got no coverage).
On smaller projects, they would just pick one of the guys who had a green badge, upgrade him to foreman's pay for the shift, and have him do the coverage.
Since then, they have been hiring a bunch of contingent workers as techs to cover outages. They are all PWU members as I am told.
Managers belong to a union called "The Society". Some of the supervisors actually belonged to both the Society and their own trade unions at the same time.
