so i work morning shifts every other day, and i requested to change my availability so that im working weekdays only, and taking off the one weekend that i work. i didn’t completely change my availability, just shifted it so that i have a schedule that makes more sense. (my manager likes scheduling me, for example, from 6-2pm one day, then 6:30-1:30 the next, then 12-8pm one day, and my schedule is so all over the place that i just need a set schedule rn.) the thing is, the second i sent my request, my manager immediately denied it without even looking at it. it was a 1 second period between me sending it and him denying it. he also tends to schedule me on days where I can’t work (no i don’t go in) but I’m just wondering what i should do moving forward? it’s an issue I’ve been having with him for weeks.
