I’m a remote employee and have been making my own schedule for the last 7 years across 3 companies and 3 different roles.
The key is finding companies that are entirely remote. Not hybrid.
Answering emails all day sounds awful. I’m fortunate enough to be able to almost entirely ignore email. Out of curiosity, what do you for work? You said technical, but sending emails for 7 hours per day sounds more like sales. I’d highly recommend quitting and finding a remote job that doesn’t require you to do idiotic busy work if you’re interested in doing things like snorkeling and hiking in the middle of the day.
