I have only tele-commuted on teams where most or all of the team also tele-commuted, often from different timezones. Some jobs there was no corporate office even if I had wanted to work in one. It would be much harder to be on a team where most of them are together in an office, able to talk face-to-face. Also tele-commuting is not a work/child-care combination. I have a separate office. When my kids were young, I always had full child care coverage, as though I wasn't there.
Hello, I'm Jean. I didn't answer the first question because I have tele-commuted for a very long time. My entire interaction with co-workers is over email, github, slack, hangouts, etc.
