"We are launching this new experience to make it more clear which YouTube features rely on watch history to provide video recommendations" - this almost sounds like a veiled threat like: We're doing this to show you that you really DO want to drink the Kool aid because you definitely won't like what we have in store for you otherwise.
At the very least, it seems like they expect most users to dislike the idea and leave history on.
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.
