I love the weird and fucking stupid viewpoints on scheduling here. Oh, can only open on weekends? fuck, I don't know what his situation might be, this person might have medical needs that come up, maybe even, gasp, religious, FUCK UP THE REST OF HIS SCHEDULE. FUCK THIS GUY.
Or, the scheduling may be due to a confluence of complications that arise from a large and overly complicated system. Hours may be more available for closers, your team lead may actually LOVE you being the closer because you have good work ethics and doesn't realize that maybe you would like to toss things up (they have other things on their plates after all). Or, maybe, the scheduler is lazy and has you set up to drop as a closer. You won't know though! You won't, unless you ask! Sometimes there are also schedule complications where the other team members may only have availability to work mornings or afternoons (did you know that some of us have fucking obligations OUTSIDE of work and we have leaders who actually understand that and are willing to work with that and not be spiteful about it?) Maybe they also just get scheduled like that because it's just easier.
I get weekends off, plus I only work mornings. I'm not special, or in medical need. I just negotiated better than most of the people. My position also allows it more readily. You can get their too, but don't rest on those laurels because if you get that fabled position of weekends off then you have to beat off the rest of the raving horde trying to vie for it.
