Whether or not working remotely is productive is really a matter of the individual. The first two responses were good - however, my experiences are completely different. Living in the Northeast, I appreciate the opportunity to do so when the weather is bad during the winter. However, I have found working on site is much better for me. Not just for production statistics, but the interactions with others means I get answers to my questions quicker plus I can help people who may come to me for assistance. Yes, there are the electronic methods to communicate, but face-to-face, when possible, has always been preferred. Shutting out office gossip or politics is no different than shutting out distractions at home such as kids, pets, non-business phone calls, etc. This isn't to say the other two respondents who like working from home are wrong - just that for me personally, I much prefer to conduct my work and business in the office. Also, again a personal preference - I find it easier to separate work life from personal/family life by working at the office. Separate places help that as I have found the days I do work at home, I keep work life in the home for a much longer period before shutting it down for the night.
Just my $0.02 - thank you.
