Pros
Auto-Chlor has very competitive pay. If you are an ambitious, hard working person, you will be both praised and compensated for your efforts. The route position offers nearly 100% autonomy, so if you can effectively manage your time, you can be your own boss! The workplace culture is fun, laid back, and results oriented. It's not a "good ol' boys" union style workforce, you earn your own merits through success not hours worked. Everybody is a team-mate and a friend, the guys in suits upstairs included.
Cons
The work is not easy. There's a bit of a learning curve, and some days can be very long. Inversely though, some days can be short. It may take months to master the trade, but once you've reached your stride, it's very fun and rewarding.
