On the contrary, I find it quite easy. In the last year or so I've been to the empty office three times: twice to restart local VPN, once to sign a contract because I was switching companies.

I'm definitely going to be looking for remote positions in the future.

Are these jobs where you don't have to work more than two hours a day like OP wants? Sure there are remote sysadmin jobs but not these kind of jobs where they just want a warm body in a chair.
