I am not a healthcare worker, but many years ago, I took an EMT-A course. Although I never joined a squad, it was still valuable training.
When I was doing the hospital ED part of the training, they sent me out to the curb, by myself, to transfer a patient from the front passenger seat of a car to a wheelchair. There is only enough room for one person inside of a car door. I am a smallish male (5'8" and about 150 pounds then). Luckily for me, she was a little old lady, and I was able to place her into the wheelchair without difficulty. As soon as I got her inside, someone was waiting there to take care of her.
At the time, I wondered why they kept having me assist with lifting patients, when we never studied that in EMT-A school (they also had me take rectal temperatures on a 12 year old boy, which was something else we never practiced, but that's another story). It was not until I started reading this forum that I understood. Unless there was a male doctor, I was the only male in the ED, and I was taller and stronger than the females.
As a smallish, nonathletic male with thick glasses and allergies, it never occurred to me that I was the best available choice for physical labor.
