Here's a tip from someone within Caesars, which was sent to me today:

The security department officers are not happy with the present forced 4-day workweeks, which are in 12, 12, 8, and 8 hr shifts.

The day shifts are 7am - 7 pm, 11 am - 7 pm. Night shifts are 7pm-7am, and 11 pm-7 am.

Coverage on the casino floors is sparse to say the least, and they aren't hiring full time security officers. Morale is low at the moment.
I'lll agree that working mandatory 12 hour shifts twice per week has to suck.
