Kevin Gilliland, network and sales director at the Post Office, said the Communication Workers Union's (CWU) decision to strike will "cause disruption to customers."
The CWU are calling for an above-inflation pay agreement when last year our overall performance was a loss of £116 million.
We must reverse this loss of public money. Strike action can only cost our people money, cause disruption to customers and threaten our plans to turn the business around and keep our branches on high streets and in city centres across the UK.
The CWU's call for its members to stop proactively introducing financial services to customers is extremely irresponsible.
