On Friday in Paris, many travelers were delayed as a result of the strike conducted by border police. The border police, who are represented by the Alliance Police Nationale union, have already held two strikes earlier this month. The officers have lost a number of benefits recently and have elected to hold these strikes as a result. Union representatives have discussed compensation with government officials but have still not come to an agreement.
