PeopleScout, like many companies now, has a much larger group of remote employees. Every company has their unwritten rules for how their employees interact with each other daily. For example, many will default to phone calls, but won't go as far as doing a video conference.

If you really want to drive better collaboration over time, or put a smile on the faces of your coworkers, put yourself on video one day. Tell those in the meeting that you wanted everyone to see you today. It's a great ice breaker to change the mood of what may be a regular meeting in a positive way.  

What do you have to lose? Show your smiling face to your coworkers when they don't expect it, and I guarantee you'll see a positive reaction. Put yourself out there from time to time in an unexpected way to keep those sometimes mundane meetings and interactions fresh, it really makes a difference.
