I suspect like some folks here, my personal (negative) interactions with unions have turned me off of unions in general. I worked at an unionized shop when I first graduated and while I recognize some of the positives the union brought, there were also many downsides.
Some examples:
- Nepotism. We had an open position we couldn't fill for over a year because one of the union leader's son was graduating soon and that position was reserved for him.
- General complacency. Raises and promotions for the most part weren't based on performance, but rather tenure. Many people start off ambitious but end up just doing the minimum over time because there is no reward in trying too much.
- Strange (from my perspective) rules. I couldn't have more than one CAD going at one time, and because CAD is backlogged the turn around time was super long. This meant for long stretches of time I couldn't do any work. But I also couldn't leave. I read a lot of wikipedia pages during this time.
Eventually I got super bored, didn't see any growth potential and wasn't learning much so I left.
I assume not all unions are like this, but I do hear things similar to this from others (many on this thread) quite often as well.
