^that sound plausible.
However there could be issues.
Like getting ahold of Troi, at a time she is supposed to work, she is hiding on the bridge...
And are officers with children on permanent "day" duty?
Or if someone is working "day" and hos to visit a "day" based service?
I realize that these are simple scheduling issues and a regular switch of shift hours could solve them.
By the way would maintenance be done during day or at night?
Also if we take E-D's 3 shift schedule:
0-8
8-16
16-24
I could see Crusher taking the 16-24 bridge duty, and Data the 0-8.
