I have found the biggest hurdles to remote work usually boil down to one thing, your clients or employer and fellow employees, who still "go into" an office, need to buy into the remote worker situation. This usually entails wrapping their heads around fewer meetings (even adhoc ones) and utilizing online tools exclusively...namely Slack, Teams, Skype, etc.
What has helped tremendously is that since most companies adopted a sudden and an across the board "work from home" policy, it's forced collaboration via different avenues. Those of us who already worked from home, now are included in meetings and discussions that we would normally be left out of because our face wasn't physically in an office.
I'm hopeful that we'll see a broader adoption rate even for those that still like the physical office, will be able to work from home on an as wanted basis..sick kid....sick spouse...deliveries expected...plumbing needs fixed..etc.
