The other week I asked if I could start an hour earlier in turn for finishing earlier and my CSM was fine with it.
It probably depends on the person. I asked my CSM the same thing and he didn't care, he's generally pretty nice. But a couple of months ago I asked the 2IC the same thing and she made suuuuuuch a big deal out of it.
The was like *siiiiiiiiiggggggghhhhhhhh*" NOW I HAVE TO CALL ALL THESE PEOPLE AND RE ARRNAGE EVERYTHING"
So I said if its that hard dont worry about it
then she said No its fine I'll just take it up with Rori (CSM)
never heard anything about it, swapped it around no problems, he probably didnt care, pretty sure he hates the 2IC anyway..
