The threat of disruption to postal deliveries over Christmas in the West Midlands has been lifted after a strike ballot was cancelled.
Royal Mail said it had reached agreement with the Communication Workers Union in a row over the introduction of a packet sorting machine at the Birmingham Mail Centre.
The CWU said the company had made assurances about staffing levels and working practices surrounding the new machine, which was turned on for the first time on Thursday.
Strike action could have caused havoc for Christmas deliveries, as a possible walkout was timed from December 21.
Royal Mail spokesman Mike Dalton said: "We’re pleased that this disagreement is behind us and we can now concentrate on the important task of handling our customers’ Christmas mail."
CWU spokesman David Wiltshire said his members were "more than happy" with the agreement.
