I'm currently the logistics supervisor at Marshall Field's in Woodland Mall, Grand Rapids. We're hiring a bunch of people for truck unloading and processing, as well as people to place merchandise on the floor, etc. We're hiring part-time positions for both early morning and evening shifts. My crew is getting thin and we really need new people asap. So if you need a part-time job in Grand Rapids stop by the Marshall Field's in Woodland Mall. You can say that Seth reffered you to the position.
Unfortunately the starting pay is $7.25 but I believe they will give a bit more if you have retail experience and request a bit higher to start. The schedule is relatively flexible though so it makes for a decent second job or college job.
