French unions are famously radical and resistant to reforms. On 12 September rail workers, students and civil servants protested in cities from Paris to Toulouse against loosening labour regulations, seen as a key public test of the president’s reformist resolve. Police said there were 24,000 protesters in Paris; stone-throwing activists clashed with police, who responded with tear gas. Four thousand strikes were called around France by the country's biggest public sector trade union, the CGT. The numbers were, however, well below protests against another labour reform last year.
