Postal workers in Oakham, Leicestershire, walked out in defence of a sacked colleague on Wednesday of last week and are now set to ballot for official strike action.
The 57 workers were angry that a postal worker had been summarily dismissed after leaving the keys to his van in the vehicle while collecting mail.
The van was then stolen. Many union activists believe that increasing workloads and pressure can lead to mistakes.
A union member at the Oakham delivery office told Socialist Worker that the entire office had walked out in defence of their friend and colleague.
“The atmosphere between management and the union has been tense for some time,” he said. “When people heard about the sacking they felt management had overreacted. The worker has been at this office for more than 14 years, and is very popular.
“We are now balloting for action and I expect that we will win it. The strength of feeling that exists over this issue is not likely to go away.”
