With the spiralling cost of living in recent months, unhappy workers have increasingly been turning to industrial action as they fight for pay rises or improved conditions. It's been described by unions as a "summer of solidarity".
Relationships between union officials and companies and the Government are under strain as the latter is accused of not doing enough to help workers struggling to keep up with soaring bills. Workers have staged unofficial strikes at a number of industrial sites over pay.
Sources told the PA news agency that the action has affected construction and maintenance work. The walkouts are the latest in a series of stoppages hitting sectors including the railways, courts and postal services amid growing unrest in the face of the worsening cost-of-living crisis, reports the M.E.N.
