Raising France's legal retirement age was one of conservative former President Nicolas Sarkozy's key reforms, aimed at reducing heavy government debts as Europe sank into a continent-wide financial crisis. The reform met huge, nationwide protests - yet many economists said it didn't push the retirement age high enough.
The minimum retirement age went from 60 to 62, and the age to receive a full pension regardless of how many years you pay into the system went from 65 to 67.
On Wednesday, Hollande's government presented a draft decree at a cabinet meeting that reverses the retirement age to 60 for those who enter the workforce at 18 or 19 years old and have contributed long enough to the pension system. The right to retire at 60 was long seen as a pillar of France's social benefit system.
The government said the decree, affecting about one in six retiring workers, would be finalized later this month and take effect in November.
The decree also slightly eases pension requirements for mothers, noting "the impact of motherhood on women's careers," and for people who suffer workplace accidents.
The hard-left CGT union hailed the move as a "striking decision that breaks with policies everywhere in Europe."
The government says the costs - estimated at (euro) 1.1 billion ($1.37 billion) next year - will be financed by a small rise in payroll charges paid by employers and employees. The government did not release a global cost for the measure.
Social Affairs Minister Marisol Touraine said the decree is a "choice for justice." Critics in France's powerful unions said Sarkozy's reform had unfairly punished low-income, unskilled workers.
Sarkozy and his allies argued that French workers had it too good, while busy workers in places like China and India are propelling their economies ahead.
France's leading business lobby, MEDEF, criticized the Hollande government's decree as "worrying for the financial future of the pension systems and for the competitiveness of businesses." Conservative politicians denounced it as shortsighted.
The Socialist cabinet is making the change by decree, amending an existing decree on workers who serve especially long careers, instead of via a law, which would need approval by the lower house of parliament, currently dominated by conservatives.
