Yeah I do, just on the principle that an environment that retaliates against worker solidarity is an oppressive environment.
It's similar to someone saying "can slaves be well taken care of by their owners?" Many people would say yes, but I would say no on principle. No matter how short the work day, no matter the benefits, months off every year, etc. I would say on principle that being owned means you're not well taken care of.
The principle here being that sometimes "one" negative can be enough to mean you're not "well-taken care of".
