French public sector staff will join rail workers in striking Tuesday to protest reforms proposed by President Emmanuel Macron, with the country braced for possible major disruption.

The stoppages are part of a series of demonstrations by public sector employees against Macron, who has pledged to reduce public spending, trim jobs and overhaul large parts of the vast French state.

All unions representing civil servants have backed Tuesday’s strike, a rare show of unity which was last seen around 10 years ago, The Local reports.

Their walk-out, which will affect schools, public kindergartens, flights and some energy infrastructure, is the third stoppage since Macron’s election in May 2017. “Thanks to the civil service, all of the unions in this country will be together,” said labour leader Bernadette Groison from the FSU union. “That shows how high the stakes are.”

The centrist government plans public sector reforms next year which would lead to the greater use of contract workers for some state services and a cut of 120,000 jobs by 2022 out of 5.6 million.

Many civil servants fear that the government plans to scrap their special status and job-for-life privileges, a measure that has already been announced for new recruits on the state railways, the SNCF.
