My experiences dealing with unionized workforces in Canada as a customer/consumer have generally not been good at all.
Such workers often exhibit tremendous inefficiency, a lack of care, and disinterest. This results in low-quality service/work, and a bad experience for the customers/consumers involved.
This is particularly noticeable when dealing with government employees who are unionized, such as public school teachers, some public hospital staff, the police, public transit system staff, and bureaucrats.
Unionization in such cases creates an environment where there's no incentive to perform well, as there's pretty much no downside to the unionized worker for providing terrible service.
While private sector unionization can result in a similarly-bad customer/consumer experience, at least there's often some degree of competition involved, which can give customers/consumers an alternative when service is remarkably awful. The bad service isn't as unavoidable as it is in the case of the public sector.
The content out of Hollywood matches this pattern, too. I've found it to be among the least-entertaining, least-interesting, and lowest-quality content around. I've had much better results with content from small, non-unionized, independent creators.
