This is the first time in history that a strike has been called at the same time in the factories of the three main automobile companies.   This Saturday, union meetings were held with Ford and a meeting with GM had also been planned, according to two sources familiar with the negotiations reported by the Europa Pres news agency.   This Monday there could be a meeting with Stellantis. When asked about his formal support for Biden's re-election, Fain warned: "Our support has to be earned."   "We want actions, not words. Who is the president now, who was before or who will be later is not useful to win this fight," he argued.   "This fight has only one reason: workers want a fair share of economic justice and not to be left behind as has happened in recent decades," he said.   Also this Sunday, the spokesman for the Democratic Party in the House of Representatives, Hakeem Jeffries, was with the striking workers in Wayne, Michigan, and highlighted the "just" and "necessary" struggle of the workers.   For now, only three plants are stopped: one of General Motors in Wentzville (Missouri), another of Stellantis in Toledo (Ohio) and a Ford subsidiary in Wayne (Michigan).   "Stellantis and the UAW have entered a critical phase of negotiations," the group created by the 2021 merger of Fiat Chrysler and the French PSA Group declared on Saturday.   Stellantis raised its offer and proposes an increase of "almost 21%" during the four years of validity of the new collective agreement, compared to 14.5% a week ago.   For Fain, an offer of 21% is far from enough and he understands that employees deserve the same 40% salary increase granted to the manufacturers' managers, although he reiterated that the union agreed to lower its demand to 36% in four years. .   "We don't even want to hear about 21%," he declared this Sunday on CBS. GM and Ford offer to raise salaries by 20% in total
