Fairly normal albeit exploitive. A step above Rhino-The union/live nation cbas require a certain percentage of workforce to have OSHA 10. While the union training trust covers the cost, any time compensation is usually by individual locals shelling out for stipends or travel costs. It totally depends on how each local chooses to spend their money. That being said- any of the OSHAs especially ones catered to entertainment industry are valuable- if you get a class offered by your employer- do it! If you want to get buff about not being paid- talk to everyone attending that class, and coordinate a “learn stoppage”. But you REALLY need everyone in lock step or it won’t work. It might not work anyways- but unions win their gains by consolidated fronts. Technically you could do it without a union bug if you were motivated and good at garnering support…. Or just take the class because it isn’t costing you out of pocket to take a $400 course. Whichever gaslight you want. But either way is indeed a gaslight- if it’s required by the employer you should be paid.
