A few months ago I heard an NPR piece discussing telecommuting. Don't recall who did the survey.
The gist of the piece was years ago folks though telecommuting would be a boon to folks who could not commute: disabled, part timers, working mothers, etc. that it would make it easier for these mobility restricted folks to get into the market place.
The observed data suggested that the folks actually doing the telecommuting were high functioning people with an existing job, they were using telecommuting to EXTEND THEIR WORK DAY. So they would go home and work in the evening.
So rather than expanding the work pool it has worked to concentrate available work into the hands of those that already have it.
My personal observation at my company is mixed. There are a lot of folks who work at home, because the company gets rid of office costs, shifting that to the employee. There are also a lot who have no real office, they are flying several days a week, working 60 to 80 hours a week. Middle management.
The clients seem to expect this kind of behaviour. It is common to receive client demands right before a holiday with a due date right after. Happened this week. We have been negotiating a job for a year. Tuesday at 3pm we received an email requiring significant redesign, computer simulation runs, with a response no later than 10am Monday. Final negotiations 10am Tursday. Luckily for us our partner responsible has overseas engineering staff that does not celebrate Thanksgiving. No so for our competition.
I have seen, more than once, a client issue a large and complicated RFP the week befor (or of) Christmas with a due date immediately after New Years. One year I spent the entire Christmas holiday, including my vacation time, helping my Wife respond to a City mandated policy submittal that ended up being a few hundred pages.
Not exactly "telecommuting" but it does point to how the division between work and home, be it place or time, is dissolving.
FWIW, in our retirement both of us will be continuing to work on some part time basis, she with regular hours, I will be on call, or "casual" as they call it. But it will all be over the phone, from our boat.
