if you want hours, we do have them. Does it mean you have to work split shifts or more than 5 days. Yes. Does that suck. Absolutely.
I'm sorry but that sounds like you're dangling payroll over their heads saying "you want this? You're going to have to do things for us that you're going to hate yourself for". It's almost like Big Tim decided to get a legit job.
I get requiring people to have a fairly open availability. I can't even begin to count the number of applications I turned down from people who want to work 9-5 M-F. However, requiring split shifts and 6+ day workweeks is a sign that either:
1. Your store is staffed by even bigger asshole ETLs than most of us deal with or
2. Your HR hired a ton of people with very limited availability and you're in a bind.
It's not their obligation to provide you with hours. If you don't want to work by their hours find another job. I see people at the computers applying for a job every single day, Target isn't short on people who need a job. They don't owe you stable hours or a set schedule each week. You agreed to work at Target, I promise you they don't care if you walk out. If they cared THAT much if you left you would have been promoted. We live in a world where our labor is cheap and easily replaceable by someone who is probably more qualified.
