Record-Keeping: Heed federal rules for discovery of e-mail, IMs

American workers can access the Internet, e-mail, instant messaging and other forms of electronic communications from anywhere at anytime. While electronic communication helps people do their jobs, it also leaves a trail. A telephone conversation relies on the memory of two participants, but e-mail and IM discussions can be preserved for years to come. And, given the casual way so many people fire off e-mail these days, that can spell legal trouble for employers.
