12-hour vs 8-hour shifts
The oldest argument in policing, and it is not really about hours. Both add up to a full-time job. What changes is how many days of your life the job takes.

Fewer days, longer days
A twelve-hour rotation puts you at work about fifteen times a month. An eight-hour rotation puts you there about twenty-one times. Same full-time job, six fewer days out of your life — and six fewer commutes, six fewer sets of gear on and off, six fewer briefings.
That is the case for twelves in one sentence, and it is why most agencies that moved never moved back.
The case against
Hours ten, eleven and twelve are not the same as hours one to three. Fatigue research is consistent on that, and any officer who has worked a busy night knows it without needing the research.
A twelve-hour day also leaves very little on either end. Sleep, eat, get ready, go. Anything that needs an evening does not happen on a workday, which is why the days off matter so much more on this pattern.
Hours worked is not the same as hours paid
Most twelve-hour rotations average forty-two hours a week rather than forty. Most eight-hour rotations come in at thirty-seven or thirty-eight. That difference shows up in your check and in how much overtime is available, and it varies with your work period and your contract.
It is worth knowing which side of forty your pattern sits on before you argue for a change.
The part nobody mentions
Court. On a twelve-hour rotation you have more days off, which means more chances for a subpoena to land on one. Officers moving from eights to twelves are often surprised by how much of their new free time goes back to the courthouse.
