The Communication Workers Union (CWU) said its members based in the Wirral have voted to strikes over a “petty, vindictive attack” for sacking four postal workers as they took a tea break.
Postal workers have joined forces and are angry as there is a “culture of bullying” at the Prenton Delivery Office.
A CWU spokesperson said: “The result is a clear demonstration of the anger workers feel about this petty, vindictive attack on their respected colleagues.
“It is a clear rejection of a culture of bullying and mismanagement in the workplace.
“This situation won’t be solved by management doubling down on poorly handled decisions, but with a decent compromise that sees these workers reinstated and the workforce treated with the respect they deserve.”
A Royal Mail spokesperson said: “We have received notification of the result of a local ballot at the Prenton Delivery Office.
“This is disappointing, however, we will continue to engage with the CWU and seek to secure a resolution. We will have plans in place to maintain service in the event of any industrial action.”
