They way the dept. I worked for handled schedule requests. Instead of encouraging putting in requests off ahead of time management wanted a text the day of. My calander appeared one week the morning of the day I had a shift and didn't match what my coworkers had. I told them I wasn't scheduled on a day they all were scheduled and they insisted I still needed to come to work how did I know where to report to work if I was not scheduled (because every night you are scheduled at a different store and the locations are listed next to the date of the shift you are scheduled to work.) or call in.
Also I never met the manager of my team in person, the only communication was thru email and text message. When I had questions about when I could expect my paycheck or when there were last minute changes with locations I was treated like I was annoying her.
They mail your paychecks.
The team lead I had lacked communication skills and my training was left up to a coworker that professed how much she liked working with me but would constantly throw me under the bus when the team lead would ask why things were not done correctly.
You report to different stores around the city each shift.
The dept I was assigned to was scheduled overnights.
I felt like the team lead was overly critical of me even though I stayed at the assigned work area and didn't leave unless I was on break, and was 30 minutes early to my shifts, while there was a coworker that constantly was at least an hour late and instead of staying and working at his assigned area would not put product on the shelf right and would literally wander around the store and took multiple breaks and was never reprimanded.
Changes to work locations were always last minute and incomplete. One location change i received verbally but I requested an address for and never was supplied with.
They don't tell you what you need to do to ask for a day off, the team lead I was supposed to notify when I asked for a day off, his contact info on the website was incorrect. I had to ask for it and it seemed like he would only give it out at his discretion.
