A government proposal to liberalize the country's trucking industry prompted a strike Tuesday that blocked traffic in major Greek cities, reported DPA
At issue is a proposal that would allow any holder of a lorry driving licence to automatically receive a transport licence. Until now, the number of transport licences in circulations has been kept limited, making them valuable to possess.
Current holders protested the suggested policy, arguing that it would dilute the value of the licences, which cost some holders 300,000 euros (382,000 dollars).
The licences regarded as a form of pension by many truckers.
In protest, dozens of tankers and assorted trucks blocked streets in the centre of Athens for three hours, creating traffic chaos.
The issue prompted work stoppages earlier in the summer, when striking drivers disrupted the flow of goods across Greece. The drivers only returned to work when the government ordered them to do and also pressed military vehicles into service.
