Nine unions representing 5.4 million public workers joined together to call for a day of nationwide strikes and demonstrations to show their "profound disagreement" with Macron's bid to transform the gargantuan public service, AFP reported.
The protests are the fourth round of demonstrations in France since September aimed at forcing the 39-year-old president to row back on his reforms, with the government's response being closely watched by European allies and investors.
There has been vocal criticism of Macron's policies from his opponents, but so far fewer have taken to the streets than against previous governments forced into major U-turns by crippling industrial action and protests.
"There are a lot of people mobilized... we need to hear these worries," government spokesman Christophe Castaner told France 2 television on Tuesday in conciliatory comments toward the demonstrators.
But Prime Minister Edouard Philippe signaled on Monday that the government had no plans to change course, though telling public sector workers they were “not at all unappreciated.”
Tuesday’s day of action was the first time in a decade that all nine public sector unions have issued a joint strike call, but there appeared to be limited disruption on the national railways or in schools.
Only 17.5 percent of teachers walked out, according to the Education Ministry, while trade unions put the figure higher at 35-50 percent.
Around 30 percent of flights in and out of Paris and other major cities were cancelled as a precaution. Hospital unions also called on medical staff to walk off the job for the first time since 2009.
The demonstrations come as Macron –painted as a "president of the rich" by leftist critics – continues to take heat for a string of derogatory comments about discontented workers.
Pensioners and truck drivers are among those who have demonstrated in the past month. Regional governments are also fuming at having their funding from Paris cut by 450 million euros ($529 million).
