So it really depends, I see a lot of responses below and it really depends on your ability to work and focus (everyone is different), but for me, personally, I have a KVM and I have different setups for different levels of concentration. Nobody is ever 100% productive, don't try to be. When I start work, I log in and put my work system on my main monitor and focus on my morning work routine. I triage things as needed (I support many different systems), then I take a break to grab a coffee and take care of my morning routine. I return and work on anything important first and depending on how things go may do another work task or 2 before lunch. After lunch, I triage anything new that's on my list, then shift work to be a secondary focus for a while (personal system as main monitor, work system off to the side). I do this for about an hour, after eating it takes time to regain full productivity. Then I shift back to my work system, on my main monitor, do some more work until people start leaving the office, once things are quiet, it becomes secondary until I log out for the day. This mimics real office life to some degree, it adds in time to de-stress and take it easy, but it allows you to maximize your productivity in bursts without getting burnt out. As for teamwork, I personally prefer group chats when there's an issue we're tackling, but I'm always a fan of a quick 1 to 1 phone call to discuss things, when needed. People always know if they send me an IM, I'll be there and willing to help. Biggest mistake I see people making - Feeling guilted into working until burnout. Put in your 40 hours, don't expect 100% productivity, but do your best and take the work seriously.
