When asked recently by an HR manager if she had a sample of a policy about working from home, Pam Ross’ answer was:

“Get your work done, meet your objectives, and do it from wherever you want.”

Really, within reason, does it matter where your employees do their work, as long as they get it done?  Work is not a place you go, but something you do.  Just remember to be abundantly clear about what their work responsibilities and objectives are.
