E-mail is unavoidable for most workers but is in dire need of change, says Neil Murray, tech chief at U.K.-based Mimecast. Until that happens, some European companies are taking action. Volkswagen workers in Germany no longer will be able to send or receive e-mail on their BlackBerrys during nonwork hours, the company announced. Chemical company Henkel declared "amnesty" from e-mails during the holidays. "I don't have to read my e-mails simply because someone somewhere is bored and sending me them," said CEO Kasper Rorsted.
