In LA the 12 hour day, as I have been told, is based on fixed days off. There are two day off groups, Mon-Tue-Wed and Thur-Fri-Sat. You bid for a day off group. For example, officer A is low on seniority and his days off are Mon-Tue and Wed and every other Sunday. Officer B is higher in seniority and his days off are Thur-Fri-Sat and the alternate Sunday.
For me three straight 12 hour days is a bit much, add a fourth every other week and its beyond acceptable. Add to it that less senior officers may not see a weekend for years. No thanks!
I am not sure what Mr. Weis' 12 hour schedule looks like so I can't comment but I would love to put forward one that might gain some support.
A 12 hour day is long but under this plan you only work two days and then off two days. Our friends in the firehouse "work" 24 hours then off two days. Every 5th time they do this (correct me if I'm wrong) they get a "Daley Day", which gives them 5 consecutive days off. I believe this is to keep them within the 2080 hours a year. Under the two on, two off plan you would work 24 hours, not consecutively, and then be off two days. In a 4 week period you will work two 48 hour weeks and two 36 hour weeks. This means that after the 4 week period you would be owed 8 hours time and after three periods you would be owed 24 hours. This necessitates the need for a "Daley Days" for policemen. Firemen receive them on a rotating basis and this could be figured into our schedule with a minimal effect on manpower.
The bottom line to this plan is you work 2080 hours a year, work two days, off two days, and once during a three period span you are off for 6 days.
Food for thought.
