We love our email.  But, sometimes, email is our undoing.  Ronda Templeton talks about email and its travails in this San Antonio Express-News article.  Of course, she mentions how wise it is to think before you send any email.  Once sent, it is nearly impossible to bring back an email.

Every employee should also understand that if you use the employer’s email server for any email, personal or not personal, then the employer probably has the right to look at that email.  

Note her report that 95% of us check our work related email after hours.  Is that time compensable?  If checking email is required by the employer, then time spent doing so will very likely be compensable.
