Oct 14 (Reuters) - Royal Mail could cut as many as 5,000 to 6,000 jobs by the end of August next year, parent company International Distributions Services (IDSI.L) said on Friday, as the British company remains locked in a bitter dispute with its largest labour union.
The Communication and Workers Union (CWU), representing 115,000 Royal Mail postal workers, have held strikes in September and early October, and have threatened more strikes this month and next.
Royal Mail would post an adjusted operating loss of around 350 million pounds this year, after taking into account the hit from the strikes that have taken place or are scheduled, International Distributions Services forecast.
The company said there could be more job losses at Royal Mail, its UK business, if strikes went ahead during the holiday period.
Royal Mail, the former British postal monopoly recently changed the name of its holding company to International Distributions Services from Royal Mail Plc.
