Recent cases provide ample cause for concern.
Among the most widely publicized involves an employee, Ken Hamidi, who was fired from Intel Corp. in 1995. Since late 1996, he has sent a number of e-mails to almost 30,000 of his former colleagues, telling them not to trust management and warning them about impending layoffs. Mr. Hamidi changed his e-mail accounts to make it difficult for the company to block the specific domains from which he was transmitting messages. Enjoining his speech may raise free expression issues. Superior Court, issued a preliminary injunction that barred Mr. Hamidi from e-mailing the company.
