The U.S. Embassy in France informs U.S. citizens that on Thursday, May 12, 2016 several national unions across a variety of sectors have called for nationwide strikes against proposed labor reforms.
Employees at airports, train stations, hospitals, schools, and some government offices are expected to strike, which may cause disruption to public services and transportation. Persons concerned may wish to monitor local media and check with travel and transportation companies regarding the local impact to their own plans.
Even demonstrations intended to be peaceful can turn confrontational and escalate into violence. You should avoid areas of demonstrations, and exercise caution if in the vicinity of any large gatherings, protests, or demonstrations.
