A silent protest is to be held by supporters of sacked postman David Mitchell.
The demonstration will be held outside Royal Mail’s Cupar delivery office on Saturday April 2.
It was announced as postal workers across south-east Scotland prepare to vote on strike action against Royal Mail’s refusal to reinstate Mr Mitchell.
Accused of stealing mail, Mr Mitchell won his employment tribunal for unfair dismissal and a subsequent appeal and the delivery firm was ordered to re-employ him.
However, Royal Mail insisted it would not take him back and instead paid him compensation.
Mr Mitchell, of Chance Inn, near Cupar, claimed any one of his former colleagues could find themselves in the same position and has urged them to support his Deliver Justice campaign.
He said: “This is the most crucial stage of this campaign as 2,500 posties are in the middle of ballot process for strike action and we want to keep the word out there and ensure that they see the bigger picture.
“It could be any one of them next.”
Mr Mitchell said the backing he had received from former colleagues, customers and the general public was amazing.
He said: “The support is very, very important to me and I don’t think I would have got this far without it.”
Following Mr Mitchell’s tribunal, judge Ian McFatridge concluded there was insufficient evidence for Royal Mail to sustain its belief in his guilt.
Communication Workers Union branch secretary Kenny Logan described the case as one of the biggest injustices ever involving Royal Mail and a union member.
A ballot for strike action in the Fife, Edinburgh, Falkirk and Galashiels postcode areas is expected to begin within the next couple of weeks.
The seven-day notice of the ballot is expected to be served on Royal Mail next week.
If postal workers agree to take industrial action, a series of one-day strikes could be held, potentially affecting mail ahead of the Scottish Parliament elections.
A Royal Mail spokesperson said: “Royal Mail is still hopeful of finding a resolution with our union and our people on this local issue to ensure that customers do not face any disruption.
“Our customers also expect Royal Mail to do everything in its power to protect the mail we are entrusted to deliver.
“Following an investigation Royal Mail considered there to be reasonable grounds to suspect wrongdoing in relation to test postal items and Mr Mitchell was dismissed.”
The spokesperson continued: “We will not reinstate Mr Mitchell, as we believe that the trust between employee and employer has completely broken down.
“The legal proceedings have now concluded.”
