We work 4/10's. Originally only Patrol, but for the last 20 or so years, almost everyone. Currently we're on a 'Platoon' schedule. Everyone works either Mon-Wed or Wed-Fri with alternating weekends off. Goal of this was to keep the workforce separated through Covid. It's created staffing issues at the stations, but has been a boon for training. At least until the politicians noticed the out of control crime and redployed everybody.
Currently around 1/3 of all on duty personnel are deployed to Union Square to discourage the retail pirate gangs. They're supplemented by folks on overtime. As you can imagine, stripping 1/3 of officers out of the stations that are already short creates problems. To deal with that, Watch Commanders are authorized to hold over officers up to 4 hours to meet the shortcomings. In practice, it's meant that about half the patrol force are working 14 hr days at any one time. There is a massive amount of voluntary overtime going unfilled as a result. Clearly this is not sustainable long term, but the chief has announced this redeployment is "permanant". He says the department will just have to function on mandatory overtime going forward. Next up is the mayor's new plan to "tackle drug crime in the Tenderloin ". Good luck.
We haven't even rolled out the new Use of Force policy yet, which was crafted by the Anti Police activists of the Department of Police Accountability for the purpose of ending police Use of Force. The cops haven't seen it yet. When that hits, the exodus of cops is gonna look like the waves of refugees swamping Europe's borders. We should should have about 2300 sworn officers to Police this city. The ACTUAL number right now is about 1700 (down over 250 from when I came in at the end of 1991). I predict there will be around 1000 left here in January 2023.
