Congratz on the job.
My best advice try fish oil vitamins
My grandma works in a cold room all day standing
she starting taking them and her
feet don't hurt much anymore.
Thats the best i can do.
Anyway congratz again.
If it's joints, or muscles, find the time and a place in the back, or room to stretch, or something, roll your ankles, do a quick set of lunges, I'm sure that would help. congratz on the job, I know of that store, though I have never been.
Well..congrats ....for you though a bit late. But I would surely say that work needs a lot of patience...also I used to work standing on my feet for about ten hours...for my initial jobs....but I did try to have some sits you should always try to balance things....Good Luck.
