New job blues

So I just started a new job yesterday as a supermarket supervisor. Pretty good pay, great benefits and it’s close to home.

But I’m on my feet ALL DAY LONG. The shoes they provided me which are steel toe boots, are the most uncomfortable things I’ve ever worn. After a few hours it feels like my feet are blistering.

I’m also lifting heavy things which I’m not too comfortable with being 3 months pregnant. I haven’t told them yet and I know I’m protected by laws but I also just don’t know if I wanna keep this job at all.

I wanna find something that suits me more but with the way things are going, that doesn’t sound possible. Any advice?
