Why would you think there is such issues by the union??
If you were to be here you would find out.
My experience is opposite of the normal route. I started out on a large city dept. and 10 years later moved to a rural area and joined a VFD (paid on call) When I started there, they had older equipment, ran out of a station with trucks crammed so tight you had to pull out a truck to get your gear. But they had good dedicated people, and trained as much as they could with what they had. Ten years later we are in a new station, have just bought our 5th new truck (doing pre-build next week) and are running automatic with several fulltime suburban dept's around us. I actually get more training at my VFD than my career dept. I'd put them up against many smaller fulltime depts. It's inspired me to be more dedicated at my fulltime job.
It doesn't matter what side of the paid/volunteer fire service you're on, dedication is the key. If you don't care, then you should find something else to do. Yes, there's still differences of opinion on both of my depts., that's the way people are. But you can still strive to better yourself and your dept., and that should make being on any dept. worthwhile.
