Postal workers in Burslem in Stoke-on-Trent were angry last week after Royal Mail further inflamed tensions at the delivery office at the centre of a long running dispute.
Bosses announced that following their “investigations” four of the 12 workers who were suspended last year have had all charges dropped and been invited back to work.
One worker has been given a one-year written warning, one has been give a two-year suspended dismissal, and a further five have been summarily dismissed.
The result of the investigation into another suspended worker is yet to be released.
The postal workers’ CWU union launched a successful strike earlier this year that demanded an independent appeals process for all those who had been suspended.
That process will now start to review Royal Mail’s disciplinary sanctions.
Lee Baron, Midland’s regional secretary for the CWU union, said, “We always said we have no confidence in this process, which is why the independent appeal was so important.
“We are not surprised that, following the amount of managerial change directly linked with this dispute, that Royal Mail would want to walk away from this with scalps from those whose only crime was to stand up for their union.”
