In 2014 Deutsche Telekom said that since 2010 it had had a policy recommending that managers avoid sending e-mails after the end of the working day, for example at weekends. In 2013 the Goethe-Institut described the company’s self-commitment: müssen die Arbeitnehmer außer in Krisensituationen in ihrer Freizeit nicht erreichbar sein, except in crisis situations, employees need not be reachable in their free time. In 2013, at the energy company E.on, no business e-mail was allowed from 20 minutes after the end of the working day. BMW chose a different route: Wir haben uns im Wesentlichen für Vertrauen und gegen starre Regeln entschieden. We have essentially decided for trust and against rigid rules.
