In the small city where I live a police Sargeants base pay is around $76K and base cop pay is $48K, the city managers is $115K, and department heads and Chiefs is $105K. The the highest paid 8 employees were all 6 Sargeants and 2 corporals, then the manager, followed by 5 more cops then the department heads and chiefs.
Cops love that OT and will do anything to get it.
A couple sergeants I know had a sweet deal, doing overtime at the baseball park while the Giants played. Easy gig, extra money. They retired with a big smile (and big pension). They were the friendliest cops I knew, probably because of their relatively stress-free jobs.
