This has inherently nothing to do with that. We were told at my store a year or two ago that Target as a whole was "overspending on Logistics". Target would have had to bump up to $15/hour anyway because everyone else is doing it. My second job that I get 28-32 hours a week has done it and I haven't lost hours there.
This is all a ploy to cut costs by slashing out vacation, benefits, and various other things to TMs. The $15/hour is pure bait to get people to stay and a PR tactic. All of this would have happened anyway because it's all about maximizing profit any way they can. When a good chunk of what we sell comes from China that has tariffs all over it now, it means they have to slash costs with employee hours and benefits.
