I work for BT which went through a phasae of offering suitable staff homeworking - they build an office in your designated space - computer, internet, phone line, the whole nine yeards.
I have been offered it, and always refused. i enjoy the demarcatiob between work and home, and i enjoy the social interaction of an office. I have been here for thirty-nine yearsw now, so the idea of swapping to home working does not appeal at all.
Plus, the present Mrs Hughes works from home when not away working, so we would probably get on each others' nerves after a while - there is not space for two separate offices so she uses our home office in the day, and I use it in the evenings to write, and that works out fine.
