The $20 an hour was for the bottom of the food chain...like Spots version of cashier.
The other employees earn more. So the clerical person who you report your claim to earns more than most of Target's TLs. There's something to be said about earning more than just enough to get by.
Just put a sheet of paper over the info for the person who is above you and below you on the schedule. Then take your picture of the schedule. You're CYA yet protecting your coworkers privacy, IF that's what HR is truly worried about.
So is it just the new hires making $13.75 or all TMs making 13.75? Back in 2014 when I was making less than $8/hr, the seasonals were hired in at $9/hr. All of the regular TMs had to wait for their reviews in spring to be bumped to $9. That was almost 6 months later.😡
Just keep showing up! Maybe someone forgot to let you go or inform you that you were a 'keeper'. By the time someone figures out what was supposed to happen, they won't be able to terminate you because you'll have been there too long!
