>One of the things I've noticed with a number of recent strikes (not all, but a bunch) is how many are not over pay but primarily over working conditions. E.g. there was a big strike by nurses in Austin whose primary concern was woefully short staffing that was leaving nurses burnt out and making it difficult to provide adequate care.
Actualized pay is often more the issue here, however we look at or segment it (working conditions, net pay, etc). It's about the net transaction of your time for labor vs compensation. Magnitude of compensation is important because people need enough money and free time to make it worth working, but there are many ways to squeeze this, just as your example points out. Understaffing, pushing increased productivity requirements, tucking in new responsibilities, reducing benefits in some way, slacking on safety or security, etc. It's difficult to quantify all of this for most people so we often just look at pay. We'll, getting paid more than enough to live comfortably.. sure, but maybe you're working long hours to get that and stressed out of your mind. Maybe you're losing sleep. Maybe you're sacrificing your health to focus on improved business outputs.
It's an in/out situation, are you getting enough out for what you put in and that's often the issue. Any business paying market rates will be quick to point at salary and ignore everything else because it's very easy to discuss, compare, and argue about.
