Target can’t stop a TL from having a second job, as long as there’s no conflict of interest. As far as I know, TLs are required to have open availability, although they may not be scheduled that way. The purpose of the schedule is to have the store optimally staffed for (here comes that phrase again)” the needs of the business.”That’s all Spot cares about. If Spot can do that in a manner thats fair and consistent with everyone, that’s fine, if not, it’s definitely not Spot’s priority.
How much working around of your TL’s schedule should be going on depends on a lot of factors. Is the TL only scheduled for the prime early day shifts but never late, closing or clopen shifts? How about their weekend schedules? Are the other TLs taking up the slack? Are the other TLs ok with it or are they complaining that that TL isn’t carrying their share of the load? Is this TL worth a few schedule adjustments to keep, or are you willing to lose them over this, and don’t be surprised if you do. There’s a good chance that if a TL has a second job with scheduling priority it’s a better job than working for Spot. Just saying.
If your SD has approved this TL’s scheduling exceptions, objecting to them is really opening a can of worms…
