Volkswagen has agreed to stop its Blackberry servers sending emails to some of its employees when they are off-shift.
The carmaker confirmed it made the move earlier this year following complaints that staff’s work and home lives were becoming blurred.
The restriction covers employees in Germany working under trade union negotiated contracts.
Campaigners warned that the move would not be suitable for all companies.
A spokesman for VW said: “We confirm that this agreement between VW and the company’s work council exists”, but would not comment further.
Under the arrangement servers stop routing emails 30 minutes after the end of employees’ shifts, and then start again 30 minutes before they return to work.
The staff can still use their devices to make calls and the rule does not apply to senior management.
