Postal workers in the CWU union could refuse to deliver post sent via anyone other than Royal Mail in the new year.
The CWU union raised a boycott because of “unfair” competition, which it said had led to job losses, price rises and fewer services.
The CWU announced plans to hold a consultative ballot in the new year with the intention of boycotting competitors’ mail.
Under so called “downstream access” arrangements, private companies cherry-pick profitable bulk mail contracts.
They sort and transport mail to a local Royal Mail office where they pay an access fee for Royal Mail postal workers to deliver that mail—known as the “final mile”.
