This is the reality of the service industry today. Our youngest son owns an HVAC company employing 15-16 people, and they provide "always on" support. He is never without his phone, and depends on good communications capability, often sitting in our living room on weekends video-consulting with employees doing emergency repairs and/or installation, helping with problems, arranging emergency parts pickup. Even when he and his family are off in their travel trailer 'getting away', he always needs a good connection that enables him to catch up on billing and order supplies. One of his largest challenges is getting timely billing done to maintain cashflow.

One of the best days of my IT career was the day I told my boss if the problem was so simple he should go fix it himself.
