Any CNA’s on here that work in a hospital??

I’m coming up on 15weeks & I work as a tech in a very large hospital & I float through out it as well.. how have you guys handled lifting pts & what not? I had a talk with my manager and basically she said they won’t accommodate pregnancy but we have lifts on the floor that can be used when needed. As many of you know, most nurses don’t want to bother with lift equipment. I’m just curious to know what you guys are doing to prevent straining while helping pts and what not. My doc said he doesn’t want me lifting more than 25lbs 🙄 & I feel like if he were to write me a restriction note my job would let me go.. idk, I’m just worried & I feel like I should may he call HR this week. Thoughts?
