In a traditional workplace, were always taught to value "workplace" over "work" and to never stay at a "workplace" for the "work". That is, if you have a crappy boss and toxic culture, working on a shiny greenfield project isn't going to help and most will advise you to leave and pursue a "workplace" that is more aligned with you.
With academia the dynamics are completely different because now "work" and "workplace" occupy the same space, as in they are equally important, with "work" might be even more important than the "workplace". So you get into a situation where you hate the "workplace", but unlike the traditional workplace, you can't simply up and leave because your "work" is far too important, and continuing your "work" at another "workplace" is from everything I read about academia, difficult to say the least.
Not sure how unions will look in academia but it's clear that we need some sort of arbiter in that space to re-balance the "work" and "workplace" since the dynamics are so different.
