SOUTH Yorkshire's postal services look set to be disrupted after workers voted in favour of a national strike.
The Communication Workers' Union (CWU) said 76 per cent of those who took part in the national ballot voted for industrial action in a bitter row over jobs, pay and services.
It was described by union bosses as a huge vote of no confidence in Royal Mail bosses–but postal chiefs have slammed it as "irresponsible.
The union will have to give Royal Mail seven days notice of a strike, which would disrupt deliveries all over South Yorkshire.
The dispute centres on Royal Mail's modernisation plans which the management says are essential to improve efficiency.
