If you admit to the person who lets you know you've got the job, that you need help lifting more than 30 lbs you won't get an orientation day to actually be hired. If you while working you get hurt and your doctor gives you a restriction letter that you aren't allowed to lift, push/pull, or raise something with your arms above your head that weighs more than 10 lbs you will be put on LOA (leave of absence) and fired three months later, even if there are jobs you can do to continue working. Get everything in writing from them and to them, not verbally so you can protect your income!!!
