I've worked in this situation and it worked out great, and I've worked in this situation and it was terrible. There are a couple of things I would say are key:

- Everyone has to use the same communication tools, ie everyone in the office has to be using Slack/Hipchat and regularly do hangouts with remote people

- All meetings have to assume someone is going to be remote. It has to be burned into the culture that when you have a meeting a laptop is open and hangouts/gotomeeting/etc are running

- Annual onsite is a must! I've been amazed how a few days of in person communication can form pretty deep bonds. Once that username has a face and some shared inside jokes they become human forever. Anyone more key on any team should also strive to make it out around quarterly. I think everyone has people they'd consider good friends that they only have met in person one or two times while attending a conference or visiting a far away friend, same goes for the office.

- Let your local people work from home when it makes sense! Don't make your office people trudge through feet of snow while the remoters sip hot cocoa at home. In my experience most people working in the office actually like working in an office and most remoters like working remote. But, whenever possible, let the local people stay home if they need to wait for a package, take care of a sick kid, need some time to clear their head, the office is under construction etc.

Even though it sounds like the smallest one, the chat one is actually one of bigger issues. If everyone is on Slack you'll find even people in the office start using it to communicate with people a few seats away for small stuff, sharing links, conversations you'd prefer to be quiet etc. And this eventually means that communicating with someone 10 ft and 10k miles away feels very similar.

I actually introduced Slack which is much better than Google Hangouts; having any sort of shared chat room is much better for team cohesion but I feel there's something missing the culture because we don't constantly chat. At my last workplace we had no one remote but since everyone was on different projects the Slack #general channel was the place to make sure you get that cross-team and company-wide communication happening and to have fun. Here with 25% remote and 75% in office it feels like the watercooler and team cohesion aspect can't ever really happen.

Your advice is sound.

This pretty much reflects what we have learned as well.

I currently work on a team that is about 50/50. For some reason it doesn't seem to create any issues.

I think the reason is that the team has always had remote workers, so there was never a time where teams were 100% in office.

We are approximately half remote actually. We just treat every interaction as if everyone were a remote employee.

Obviously not EVERY reaction, but if that is the default, it's quite easy to sustain.

it can work as long as you don't treat the remote workers as second class citizens.

On the other hand, it is annoying to be one of the people on site with a remote team in an environment where other divisions are not remote. In some cases you become the person that gets interrupted all the time while the remote workers get to be productive.

I'm a non-remote worker who agrees with the article - I definitely benefit the more things are done via chat/web conferencing. Even if I'm at the office part of the day this gives me the freedom to sit in a park or coffee shop without guilt of missing something integral.

Not if you give the workers the option to work remote or not. Believe or not there are many workers who prefer to be onsite. This is the case in my office, the onsite people are more social and want to be close to the core of communication.
