That's awesome - my eyeroll coworker is the one who has been telling me for the past 3 weeks that I'm not supposed to lift or carry those 40# buckets and boxes. I'm only 15 weeks, and at my last job I was routinely throwing around 50# bags.
Instead of slapping her, I just let her know when I spent the last 20 minutes in the freezer restacking pallets of supplies (in my head, sticking out my tongue)!
Way to go on the restraint - I might have actually had to stuff my hand in my pocket to refrain from slapping her! Of course, there are always pregnancy hormones to blame if that itchy slapping hand flies!! :)
Good luck!
