I got sick of that myself and got an electric screwdriver, which helped a lot. Keep in mind that I did all the low voltage wiring in the house myself, it was a couple thousand feet of wire. A lot of it was overhead work - boring holes in the joists, etc. I wouldn't say it was pleasant, and lifting that heavy 90 degree Milwaukee drill was a chore.
But I did figure the electricians knew what they were doing, so I watched them. I bought the same tools they used, and went to work.
Electrictions can work over their head with screw drivers for weeks at an end. There are plenty of bad working positions for their body.
