+1, a large portion of my family are in health care, many have since left not due to the job, but in some cases they couldn't deal with some of the arcane union practices. My sister had the example of a ward being rostered for 4 staff, but 6 turned up for duty. A separate ward was down 2 staff due to "sickness". However, the manager couldn't send the two off the surplus ward to the short ward due to a union agreement and had to go to an agency for two temporary nurses for the short ward.
So she spent an entire shift with two people who actually did nothing, while fees were paid for two agency nurses who weren't needed. It wasn't a one off.
