Nancy Garrity and Joanne Clark worked for John Hancock Mutual

Nancy Garrity and Joanne Clark worked for John Hancock Mutual Life Insurance Company. On their office computers they regularly received sexually explicit e-mails from friends and from Internet joke sites, which they then sent to coworkers. When a fellow employee complained, Hancock searched their e-mail folders and, finding inappropriate e-mails, fired the two women. The Hancock e-mail policy states:
“Messages that are defamatory, abusive, obscene, profane, sexually oriented, threatening or racially offensive are prohibited. Company management reserves the right to access all e-mail files.” The two employees filed suit against Hancock, alleging that the company had invaded their privacy. How would you rule as judge?
