It is difficult for people to stop working. Many workers look at e-mails on the train, at lunchtime, at home, and when they are on vacation. Workers for the carmaker Daimler can delete e-mails and relax when they are on holiday. Daimler says it wants workers to enjoy family time and "me time" on holiday.

Daimler said staff work better after a refreshing holiday. The company said staff should relax on holiday and not read emails. Its mail system sends replies that ask people to write again later. This might be a bad idea. Some people won't write again. Companies could lose money.
