Working @Amazon while pregnant

Working a warehouse job while pregnant is so hard in my experience. I’m currently 16 weeks and my body is begging for as much rest as I can get. Amazon offers accommodations, but for some reason my manager is making it hard for me to get approved. There’s a handful of females sitting down their whole shift for accommodations & I just get a few extra breaks. It’s stressful witnessing them gossiping or being on their phone instead of doing laptop work. Especially when you know you’re standing 10hrs+ and doing labor.
