Despite the organised strike action by postal workers finishing this morning there have been reports of some unofficial strike action continuing in some regions. Staff at more than 20 delivery offices including parts of London, Glasgow, Merseyside and Lancashire have continued to strike in protests related to their working hours. Some reports suggest that staff continued to strike after turning up for work only to be told that their workings hours had been changed without prior agreement. Mail posted to the affected areas will be subject to further delays.
