i use one of those trackball mice with the ball on top. first time i tried it i never went back, no need to worry about having a proper surface or desk space for a mouse ever again. if you reach the side of your desk using an optical mouse, you have to pick the mouse up and move it all the way to the other side of the desk, while is a proper ball mouse (a good one without too much resistance) when you flick the ball it can continue spinning a bit even as you release it, so you can flick it to the side and then bend your wrist slightly to then flick it again, and the mouse cursor will just continue moving without stopping, which in games you can do this to have endless turning around, when turning is always stuttery on an optical mouse due to hitting the end of the desk. it takes a little bit to get used to, but at least a good one with limited resistance and a large ball, you can easily get just as accurate as an optical mouse as well. the only downside i find is that i do have to take the trackball out and clean it like the ones on the bottom.
Che Guevara wrote about in his book Critical Notes on Political Economy about how workers who are given full autonomy in their enterprises actually can become antagonistic towards society because they benefit solely from their own enterprise succeeding at the expense of all others, and thus they acquire similar motivations to the capitalist class, i.e. they want deregulations, dismantling of the public sector, more power to their individual enterprise, etc.
The solution is not to abandon workplace democracy but to balance it out also with public democracy. You have enterprises with a board that is both a mixture of direct appointments from the workers at that company with their direct input, as well as appointments by the public sector / central government. The public appointments are necessary to make sure the company is keeping inline with the will of everybody and not merely the people at that specific enterprise, because the actions of that enterprise can and does affect the rest of society.
Workplaces need to be democratic, but also not autonomous from the democratic will of the rest of society.
