Strikes by French air traffic controllers coincide with on Tuesday labour reforms protests by some unions and students in Paris city centre.
Last week, some students and union groups protested the French government over labour reforms, after a week, they returned to the streets again.
Furthermore, the second strike in the city centre by French air traffic controllers are expected to cause travel chaos for thousands of passengers on Thursday.
Paris Charles De Gaulle airport was affected by the 36-hour walkout by air traffic controllers' second strike.
Hollande’s socialist government said the priority is to prevent the protests by unions and students from turning violent, as they did before.
Thousand of students and workers took the street of Paris in anger over a week ago.
Cars were burned in Paris and more than 30 people arrested as protesters clashed with police, an official said.
Labour Minister Myriam El Khomri said this week that she understood why "such a profoundly reformist text has raised questions and requires debate.”
"It is not a blank cheque for companies," he added.
Parliament is set to vote on the reforms in late April or early May.
Meanwhile, hundreds of people took to the streets in France's capital city Paris last week to protest against a draft bill that calls for stripping citizenship of terrorism convicts and enhancing powers of state authorities even further in the aftermath of recent terrorist attacks in France.
