I don't recall being informed of anything of the sort.
That seems weird. Couldn't possibly be the case here as Target base pay is barely higher than state minimum wage. Min wage is $8.15, Target pays N03 $9.00.
I made $9.50, I went up to $10.30 when they raised our base pay to $9.00.
I think you and I are in similar scenarios though. I don't think we were lucky, so much as base pay for every paygrade went up. ie. If you had been a cashier making $9.75 you'd have been bumped to $10.50, not $11.25.
If base pay at my store went to $10.50 I'd similarly expect to make $11.50, but not $11.80. ie. Base GSA pay would be $11.50, I'd make less than that, so get bumped to that, I wouldn't retain the $0.30 over base pay that I currently make though.
