It's only flexible until someone at corporate gets wind of it, and then they're going to force you into terrible hours. We managed to make it work for the store and the team for two weeks before we were forced to change it.
And, lol, "whiney brat" for not wanting to give up time bonding with a new kid and to go to school to better themselves and their life? Give me a fucking break.
Yeah, Target rolled out new scheduling expectations that make 75% of your shifts life destroying for an adult, didn't raise the pay to accommodate the changes, and the next step up (ETL) requires a 4 year degree you aren't going to be able to get with their schedule? Yeah, completely unreasonable to be unhappy about that... /s
The ETLs at my store decided that this was a perfect opportunity to abuse the TLs, too, and not a one of them has worked past the time the closing TL comes in (3pm for us) since the roll out. I don't think any of them are even hitting 40 hours a week anymore, and their only job duty seems to be berating TMs on the walkie who dare to slip up and call for "LOD."
Yeah, sorry, it took me less than a week to find a job that pays exactly the same, and doesn't demand every waking hour of my life while my boss spends 30 hours a week sitting in their office while we try to get creative where we shove unworked freight all day and haven't zoned the store in a month.
OP, I know it's frustrating, but with wages going up all over, you're better off finding something different. Even if they make exceptions for you, it's temporary at best.
