In the FL county where I worked in the 80s, the EMS workers and firefighters were by far the highest paid county employees. They typically worked 24 hours a day for 7 days. Anything over 8 hours/day was overtime, so they got regular pay, plus 16 hours of overtime every day. I was data processing director for the Clerk of The Courts and pretty well paid, but those guys came out way ahead of me.
How is this possible? No sleep for an entire week?
