Conventional wisdom is to not be ruled by your email. Various productivity gurus offer sundry methods of keeping you away from your inbox at off hours; last year Google added a "mail goggles" feature to Gmail intended to help prevent late-night flames that you'll regret in the morning.
Some people vow never to go to bed angry. Simon Cooper, president and COO of the Ritz-Carlton Hotel Co., never ends the evening with an email unanswered.
Every manager must decide on an approach to email. Are you available all waking ours? Are there strict off-limits rules you try to live up to? How are you managing email? Please let us know in the comments.
