Post Office workers to co-ordinate strike action
The postal network is heading for an even more debilitating shutdown on Monday after 5,500 staff in the Post Office said that they were to follow 115,000 of their former co-workers at the Royal Mail out on strike, reports The Times.
In what looks set to turn into a day of co-ordinated national industrial action, 32,000 members of the Fire Brigades Union are also planning to strike on Monday. The FBU is also striking on Friday. Tens of thousands of lecturers and further education non-academic staff are planning walkouts tomorrow.
