THE Communication Workers Union (CWU) will on?Friday ask the High Court to issue an injunction against Royal Mail to stop it from taking on 30,000 agency workers.<br /><br />The CWU believes that Royal Mail is breaking the law because it is illegal to take on staff to cover workers involved in a lawful industrial dispute, according to Conduct of Employment Agencies and Employment Businesses regulations.<br /><br />But Royal Mail insists that there is no wrongdoing and says the temporary staff have been taken on to clear a backlog of post in preparation for Christmas – not to cover striking workers.<br /><br />Up to 60m items of post have built up at sorting offices as a result of the strikes. <br /><br />Postal workers have already staged five 24-hour strikes that have seen different divisions walk out in succession.<br /><br />But the latest walkouts, due on Friday and on 9 November, will see all 121,000 union members down tools. <br /><br />So far talks between the Royal Mail and the CWU have been fruitless, but talks are expected to resume today. <br /><br />The dispute surrounds pay and modernisation at Royal Mail, which is grappling with a £10bn pension deficit.<br /><br />The CWU will be represented by John Hendy QC of Old Square Chambers, well known for his work in industrial relations. Acting solicitor is Paul Statham at Pattinson & Brewer.<br /><br />A number of businesses including retailers Amazon and John Lewis have switched to different couriers to avoid disruption.
