I’ve worked in some states (mainly North Carolina) that have mandated 15 minute breaks every 2* hours on shift, 30 if you stay for 6 hours, and another 15 if you stay for a full 8. This was at a grocery store so YMMV.

I think those numbers are right, but it’s been over ten years since I worked there.

Edited: cause I remembered the numbers.

You are correct in that statement. There is no federal mandate for breaks or meals, which is super shitty. However, there is a requirement for at least a meal break in 21 of the states which vary in requirements, some even extending to normal breaks.
