It ultimately ended as several upper management thought we were too "disconnected" from the company although my e-mail was always open, phone forwarded to my cell and I was online in a company wide chat messenger during working hours. We even came on-site once a week for face-to-face meetings. But I guess some people picture remote workers negatively so we are now back on-site and all the things I took for granted during the trial year are making being on-site so much harder.
I commute an hour by car so I gave up a pay raise ~$6,000/yr. on gas alone. I haven't (and don't want to) calculate vehicle wear, snow tires, etc. I'm constantly interrupted by people throughout the day laughing at the nearby reception desk, asking me about lunch or just coming to talk because they are bored. Even right now I have someone using a leaf blower directly outside my window so I can't focus on code (why I am on HN right now). The office temperature is an uncomfortable 66F because the corner office gets so hot with the many windows it has and I am part of their HVAC line. I am using an underpowered laptop instead of my home desktop (32GB RAM, high end CPU, etc) and I require our IT Department to install all software for me because "company policy"... Needless to say my productivity has dropped.
Perhaps someday we'll be able to go remote again, or maybe it's just time to move on. I've been here now for more than 5 years and I enjoy the work I do and the people I work with but after having a taste of remote-work, it's hard going back.
