IDK about the people in warehouses, but regular Target store employees are not treated badly. I mean, it's a low hourly wage job so the expectations are low, but I didn't dislike working there. They were happy to train me across multiple teams and work with my schedule. That said, it highly depends on the branch's general manager.

They do make you watch anti-union propaganda during orientation though.

One example: they raised their minimum wage to $11 an hour and are on track to bump it to $15 by 2020.

That's a good question. I live in Seattle and have heard many negatives about Bezos and Amazon culture. Especially from SWEs who have worked at both Amazon and other tech companies. I also have gotten offers from Amazon, and they are on the low end.

I haven't heard complaints about Target. So I could be wrong, but I hope competition includes competition for talent, which means better treatment of employees.
