I am not a wealthy man but there is no way I'd sign up for using any of my employer's comms infrastructure for personal use or use any of my personal equipment

I am not a wealthy man but there is no way I'd sign up for using any of my employer's comms infrastructure for personal use or use any of my personal equipment for business use. I don't live to work and there's no reason to hand over any more info about my personal life than necessary.
