I'm in the military, and we just got a new Commanding Officer who has implemented some changes in our working hours.
Typically in home port when not doing a training cycle or some type of drill, our working hours were based off of our maintenance work list and qualifications. If you were fully qualified in your job and all your equipment was signed and verified as being up to date on maintenance, you would have a 6 hour workday 5 days a week, and a 24 hour duty day where you would stand a security watch once a week. The actual time you got sent home would be in the hands of your senior enlisted person in the division.
Our new CO decided that that wasn't enough. We now work from 5am-8pm, mandatory, every day. Every third day we will not be authorized to go home at all, so we will stand 2 watch days a week instead of 1, and will also work from 6am-4pm on Saturdays which previously was always a day off unless you had security watches.
Not sure of my napkin math, but that puts us at about 95 hours a week, minimum. This will continue until we deploy to the middle east again, which is a good ways down the road, IE a year plus. I've had trouble justifying the working hours to the guys underneath me, especially since much of the work we're doing is considered "busy work." Sweeping, mopping, painting. We've even started to break down fully functional equipment just to rebuild it again to have something to do.
How long would you be able to work almost 100+ hour work weeks? How would you motivate the people underneath you?
