Job problems... Help??

Kristen • Married for 6 years to my love 💍💏💕one angel baby👼 and one on the way!👶💖
Does anyone else work somewhere where your co workers could care less that you are pregnant? I am on my feet all day and if I sit for a minute I get treated like I'm the laziest person ever. Usually by the end of the day my feet are completely swollen, purple and painful. Is asking for five minutes really too much? I'm beginning to stress over this more than ever, I absolutely dread coming to work now. Advice anyone?
