Relations between the company and the GPMU have failed to improve. The High Court in Leeds upheld an injunction last week served by Reed Print Group against the GPMU taking industrial action.

Last week the company served a termination notice to the GPMU, which could mean that it is not recognised at the company from 25 May.
