This is my opinion.

When using a screwdriver, you would have to twist and turn. This creates friction. by creating friction, the screwdrivers are getting negatively charged.

But, rubbers are insulators(objects that hold elections loosely. Mostly non-metals). this means that rubber can hold electrons tightly; preventing any electrons from flowing. So by using rubber, electricians or one would have protection from electric shock. but if there were no rubber, there would be sparks from negatively charged screwdriver when it is attracted to a positive charged or neutral object.

The rubber hold the electrons which prevent electric shock.
