Perhaps companies should be a bit more explicit in explaining that what you do in your personal time can matter just as much. (Gillespie noted that companies have to walk a fine line there, as the National Labor Relations Board is very protective of a worker's ability to voice opinions about an employer. But I'm not talking about work gripes in a chat room with colleagues. I'm talking about the aggressive and profane harassment of individuals — often strangers — with whom a person disagrees.)
