This. Unionisation is basically an attempt to reject the reality that there isn't enough demand for all that labor to be valuable at/above market-average.
Ultimately I don't think there is a right answer and which way you choose is up to you. But it sounds like a "you can't have your cake and eat it too" situation.
Lucky are those who are passionate about things the majority of the labor pool hates but many businesses need.
Edit: Just to prevent misunderstandings, this is my opinion on Unionisation in this particular industry where there are many (private) companies. It can be a different story if your only employers are not driven by profits and losses or are not in a competitive market (e.g. a government) and I wasn't trying to make a sweeping generic statement like "all unions are always bad"
