I've worked remotely for about 10 years now. I actually don't want my employer covering these expenses. If the employer is covering these expenses it requires me to document the expenses and comply with employer policies related to these expenses. For instance, an employer may mandate what speed of Internet service I am required to have, where I always want the fastest option (gigabit generally) and redundant links. Filing more expense reports in the horrid system made by SAP also is not on my list of things I want to do.
For the ~$1k/yr or so in expenses that I'd get back, I'd rather eat it. This is less than you spend on gas to commute and that's not covered, so frankly I don't care. Just pay me a fair salary with reasonable benefits and stay the fuck out of my personal life/home as an employer.
