PARISIAN sanitation workers returned to work today amid heaps of rubbish that piled up over their strike in protest against French President Emmanuel Macron’s unpopular pension Bill.

Trash mounds of up to 10,000 tons along the French capital’s streets — reportedly equal to the weight of the Eiffel Tower — have become a striking visual symbol of opposition to Mr Macron’s decree raising the retirement age from 62 to 64.

Clean-up crews began to clear the debris from streets following massive fresh protests a day earlier. 

CGT, the union centre representing sanitation workers, said its three-week-long strike was suspended to allow for more coordination with other workers “so we can go on strike again even more strongly.”

More than a million people took part in hundreds of demonstrations across France in the latest round of protest on Tuesday.

The CGT said at least 450,000 took to the streets in Paris which saw dozens of arrests as police continued their heavy-handed clampdown on protesters. 

Unions insist the fight to have the pensions Bill dropped is far from over and they have called for an 11th day of protests on April 6.
