Thousands of workers are set to strike across the region in the coming months in what has been branded the summer of discontent.
The country is set for a level of industrial action unseen since the winter of discontent in 1978, which was characterised by widespread strikes by private, and later public sector trade unions.
Staff on the nation's railways and buses have already staged mass walk-outs, causing major travel disruption, with the chaos set to continue as more strike action was announced for July and August.
