I'm on my feet for long hours every day at work too (nurse). I went back to work after 12 weeks off. There are a couple of things I will share. If you haven't been fitted for new shoes for work it's time to check into that. I wear sneakers. I went to a store that caters to runners. They examined my gait, watched howith my foot hits the ground, measured my feet, looked at the wear on my old sneakers and then brought out some sneakers to try. They made sure I was walking correctly. They even let you bring them back within 30 days to exchange them! This helped me a lot since my leg wasn't straight before my surgery but it was afterwards. Yes it costs a bit more but I can always re-order them on line when I need new ones.
