Critics of the French president have claimed that employees could leave their jobs and just stay at home because of the generous scheme.
One of Mr Macron’s presidential campaign pledges was to give workers the right to resign and claim benefits once every five years.
According to a leaked labour ministry report, the plan will cost £12.5billion in the first year as employees could leave their jobs to enjoy the perks of staying at home all day.
It will cost £4.5 billion for each year after, it is thought.
The unemployed in France are allowed to receive benefits that are a huge 71 per cent of their previous salary for two years, up to a maximum of £66,000 a year.
At the moment, the payouts are available to people who lose their jobs if their employers go bankrupt or they are sacked.
However, the French President hopes to extend the payouts to anyone who chooses to stop working to try and encourage a society where people can change careers easily.
The unemployment benefit system is already running at an annual deficit of £3.1bn and critics think Macron’s new scheme will simply worsen the debts.
Member of the Republican Party, Xavier Bertrand, warned the move could encourage 800,000 workers to leave their jobs in the first year of the scheme.
He said: “The survival of the unemployment benefit system is at stake”.
Mr Macron’s spokesman said: “This is a form of freedom, but it is a freedom to move towards something, not to enjoy unemployment benefit to go on holiday for two years”.
Earlier this month, French civil servants launched a strike against Macron’s reforms as they claimed they benefitted the wealthy.
Mr Macron hopes to make the job market more flexible and turn France’s economy into a good place to invest with tax breaks.
