The protests Tuesday at the Goodyear plant in the northern city of Amiens come after efforts to find a new buyer for the struggling plant have fizzled. An American executive who considered buying it sent a letter last week to the French government saying that France's economic model is too worker-friendly and discourages investment.
Union leader Mickael Wamen says Goodyear "wants to bring us down to the level of a Chinese worker who earns one euro and lives in misery."
Industrial sites across France are struggling in Europe's downturn. French unemployment is more than 10 percent and rising.
