Agree with T-Tones for the most part. Though the weekends may be better for rest. Want to keep in that work primed zone going, so getting to the gym after your shift is a good idea.
Might consider the 1 or 2 muscle group workout day idea. Like SS'ing back & chest (as Arnold and Franco were famous for) or legs/hams or calves, delts and traps, etc. Whatever combo suits your needs. Also tri or quad sets work extremely well when working two muscle groups on the same workout day.
I would focus on only working 3 days a week, like mon-wed-fri or until you get adjusted to your new job and work hours.. There is the GVT (10X10), 8X8, 6X6 square root (my label, nothing official) concept also. Based on one muscle group a day. Only heavier compound exercises are used. As: mon-bench. Wed-squats. Fri-BB rows. Good luck.
