TIMELINE-Detroit Three automakers converge on 23% wage hike; UAW seeks more

(Updates with latest developments) Oct 20 (Reuters) - United Auto Workers President Shawn Fain said on Friday the union had received fresh contract offers from General Motors and Stellantis NV in the past 24 hours and all three Detroit automakers had converged on a 23% wage hike, but "there is more to be won". More than 34,000 union members working at the Detroit three automakers are on strike since the walkouts began on Sept. 15. Ford Motor Executive Chairman Bill Ford has urged the union to end the strike, which entered its 36th day on Friday, warning of the larger impact to the economy. Here is a timeline of events beginning with the election of UAW President Shawn Fain in March: Date Development March 25 Shawn Fain wins the race for UAW president; vows to take a tough stance against the Big Three automakers. July 10 The union says it will open contract talks with Detroit's Big Three automakers starting July 13. July 11 Fain says the union is not afraid to hold a strike at any of the automakers without a fair contract. July 19 Fain meets President Joe Biden at the White House as the union briefed the staff on contract talks with the automakers. Aug. 1 The UAW presents demands to Stellantis, says the union is seeking ambitious benefit increases from the Detroit Three, including double-digit pay rises and defined-benefit pensions for all workers. Aug. 2 The union presents contract demands to General Motors. Aug. 3 The union presents contract demands to Ford Aug. 8 Fain angrily tosses contract proposals from Stellantis in a trash can, citing numerous concessions that the Chrysler parent is seeking in labor talks. Aug. 25 The UAW says 97% of voting members were in favor of authorizing a strike at the Detroit Three if an agreement is not reached before Sept. 14. Aug. 31 The union says it has filed unfair labor practice charges with the National Labor Relations Board (NLRB) against GM and Stellantis, saying they have refused to bargain in good faith. Aug. 31 Ford makes a contract offer to the UAW, providing hourly employees with 15% guaranteed combined wage increases, lumpsum payments and improved benefits over the life of the contract. Sept. 1 The NLRB says it will investigate the charges filed by the UAW. Sept 6 The UAW makes a labor contract counterproposal on economic issues to Ford. Sept. 7 GM makes counteroffer to the UAW that includes a 10% wage hike and two additional 3% annual lumpsum payments over four years. Fain calls the offer "insulting." Sept. 8 Stellantis says it offered U.S. hourly workers a 14.5% wage hike over four years but no lumpsum payments. Sept. 8 Fain says UAW expects to go on strike against all three automakers the following week if they do not improve their contract offers. Sept. 11 Stellantis says it plans to make a new counteroffer to the UAW after the union made its own revised offer on Sunday ahead of the expiration of the current four-year labor deal Thursday night. Sept. 13 The UAW rejects counteroffers from the automakers and outlined plans for strikes targeting individual U.S. auto plants in what would be its first-ever simultaneous strike against the Detroit Three. Sept. 15 The UAW launches simultaneous strikes that will halt production of some popular models at three factories owned by GM, Ford and Stellantis. Sept. 16 Negotiators for the UAW and Ford had "reasonably productive discussions" toward a new contract, while officials at Stellantis said a proposal to resume work at an idled Illinois factory has fallen through. Sept. 18 UAW says it would announce strikes at more plants on Sept. 22 if no serious progress is made in talks. Sept. 20 UAW says 90 workers went on strike at Mercedes-supplier ZF's plant in Alabama. Sept. 22 UAW will expand its strikes against GM and Stellantis, but has made real progress in talks with Ford Motor, the union says. Sept 24. Ford says despite progress in some areas, it still has "significant gaps to close" on key economic issues before it can reach a new labor agreement with UAW. Sept. 28 The UAW makes a new counter-proposal to Stellantis, just one day before it was set to strike at additional Detroit Three facilities. Sept. 29 The UAW will walk off the job at an additional plant at General Motors and at Ford, said Fain. The new strike will not extend to Stellantis, which called before the scheduled 10 a.m. ET announcement to make significant changes in its contract proposal. Oct.2 GM and Ford say they are laying off another 500 workers at four Midwestern plants. Separately, the UAW confirms it presented a new contract offer to GM. GM says it has received the counterproposal "but significant gaps remain." Oct. 3 Ford said it had made a new contract offer but said a dispute over battery plants remained unresolved. Ford said the new offer boosted wages for temporary workers, increased company 401(k) contributions and had further shrunk time needed to get to the top wage rate. Oct. 6 The UAW held off on additional strikes against Detroit Three auto plants, citing GM's unexpected willingness to allow workers at joint-venture battery plants to be covered by union contracts. Oct. 11 GM, Ford and Stellantis all agreed to raise base wages by between 20% and 23% over a four-year deal. Ford and Stellantis agreed to reinstate cost-of-living adjustments, or COLA. Oct. 12 The UAW shut down Ford's biggest plant globally, saying the automaker refused to move further in bargaining. UAW negotiators are expected to turn their attention to talks with Stellantis. Oct. 13 Fain says the union will not expand its strike at the moment, but warned that members would now walk out of additional facilities without warning rather than wait until Fridays to announce new plans. Oct. 13 A senior Ford executive said the automaker is "at the limit" of what it can spend on higher wages and benefits for the UAW. Stellantis and Ford said they will temporarily lay off 1,250 employees due to the impact of the UAW strike. Oct. 16 Ford executive chairman Bill Ford urged the UAW union to end a 32-day strike and reach a new labor agreement, and warned of the growing impact to the automaker and the U.S. economy. Oct. 20 General Motors and Stellantis raise offer to striking auto workers, matching Ford's proposed 23% wage hike. Fain says "there is more to be won."
