A WILDCAT strike by postal workers in north-west England is “escalating and escalating,” after staff at two more offices walked out over the conduct of an allegedly racist manager.

CWU members at Royal Mail’s Warrington mail centre and its north-west distribution hub, also in Warrington, have set up picket lines in solidarity with workers at Bootle and Seaforth delivery office on Merseyside.

The odispute was sparked on Wednesday when a manager at Bootle allegedly made a racist comment to a Muslim colleague.
