I leave work literally every single day and cry. Sometimes during work. I hate it so fucking much. I rarely ask for a day off aside from doctors appointment and I only call in for an actual legitimate reason. Usually after going to work sick for as long as I possibly can. But when I do ask for a day off for a reason other than doctors appointments then they act like I'm asking too much. And let me add that where I work the schedule is different every week. It's just a gas station. I'm a 2nd shift cashier. If I don't work it just means someone else does. So arranging the schedule in my favor every once in a while shouldn't be a big deal. In fact for the others it isn't. There one girl who has ever Wednesday and Sunday off for church which is totally fine but she is usually given the whole weekend off without asking for it. Not to mention the other girl I work with is given weekends off without asking pretty often. I'm perfectly willing to work any day 90% of the time but when a time comes where I do want off it's made out to be a huge deal like I'm really putting them in a hard spot for asking. What I'm especially upset over right now is I asked a week and a half ago (plenty of time to arrange the schedule in my favor) to be off on Halloween so I could take my 2 year old trick or treating. I left a note on her desk. I also added that she has never been trick or treating and this is her 3rd Halloween. Fast forward a week later and I check the schedule and of fucking course I'm scheduled to work Halloween. 3-11 so Its not like I could work and take her after. I texted my manager and she took a day and a half to respond saying she never got a not and if I can find someone to work for me they she will let me be off but everyone who is scheduled to be off th ay day has kids so of course I'm not going to ask someone to forfeit their time for mine. But She also has 2 more people than usual scheduled that day so there is really no need for me to be there. None. I hate that I was ignored and I hate leaving crying every day I just want to quit so bad but I literally have no other financial option. If I quit I lose my car. The only car we have right now. But if I don't quit I may get to stressed and fucking emotional which isn't good for the baby boy I'm carrying I'm stuck. Seriously briefly considered a damn sugar daddy.
