I do telephone sales from home. I promise I only phone businesses, and NEVER people at home. It's a slightly unpleasant enough role as it is, cold calling businesses to tell them that they really want my company's services. I couldn't impose that on folks as they sit down to bath their babies or feed their families. Yuk.
Having said that, I've been doing it for years, am professionally trained, and do a reasonably good job.
Dirty secrets? Well, don't tell the boss, but, working from home does give me quite a lot of freedom......
