As pretty much everyone has said, this is NOT the norm. Maybe your STL can get away with it, or is even will to try to, but this is going way over most of their heads. Cutting TMs to 4 hour shifts was rolled out years ago, and even at my store with its frequent HQ visits, we only implemented it for a short while before we couldn't run the store with the lack of TMs. We lost nearly ALL of our TMs that could work in the middle of the day. Now everyone either leaves by 3pm or starts at 5-6pm, leaving us just deserted during peak hours.
Now, we've been forced into it again, and even the rockstars are getting drastically cut, AND turned down for picking up shifts outside of their work centers or "ownerships" - for some reason that's unclear to all of us.
People we just told a couple months ago that we would make sure to give 30-40 hours to because of their availability and work ethic, are no working the same amount of days for half the hours (and pay.)
We have ONE left TM that will succeed with the new "DBO" process. ONE.
And we're not hiring because we're at "headcount" with all the leftover flex fulfill season TMs. The ones that FF didn't want...
And to all the "if you don't like it, quit" stuff? That's painfully elitist. There are all sorts of reasons some people cannot drop everything and immediately get new jobs. The strongest right now being, if they DO happen to be leadership or a full time employee, there's been a strong trend for employers to not offer health insurance for 6 months to a year, and there's a LOT of people who cannot go without that long, making them dependent on staying at a job that they hate. Hell, even Target is making people wait for benefits now; a lot of our new leadership was extremely unhappy when enrollment rolled around.
