The word social always makes a frisson go up my spine when I hear it on the radio. It's up to no good.
action social = strike
plan social = mass layoff
logement social = housing project (also known as HLM-- pronounced AhshellEM)
conflit social = labor dispute
partenaires sociaux= the bosses (always referred to as le patronat) versus the workers, the government and the media
mouvement social = labor protest, strike
acquis sociaux [plural]= the things we have fought for, e.g. the 35-hour work week; retiring at 55; six-week vacations; the near-impossibility of getting fired for rudeness or incompetence
