ROYAL MAIL workers today voted overwhelmingly in favour of more strike action.

More than three-quarters of the Communication Workers Union's 121,000 postal workers voted for nation-wide strike action in an ongoing dispute over pay and modernisation at the Royal Mail.

Disruption to postal services could start by Thursday and last for several days, causing more chaos and delayed deliveries.

Recent regional strikes have already resulted in a backlog of 30 million letters, and could have a knock-on effect on the Christmas post even if the national strike does not go ahead.

Derek Clash, Branch Secretary of the CWU Bournemouth & Dorset, says members are "fed up with the way management are using bullying and intimidation tactics" to implement changes.

He added: "Hopefully Royal Mail will see sense and come up with a solution."

The Royal Mail is urging the union to honour its no-strike agreement to avoid any further loss of business and confidence.

If the strike goes ahead, it will be the first national action since 2007, when a massive 200 million parcels and letters were delayed.
