The Teamsters and UPS could be heading toward the nation's largest strike in decades. UPS employs 260,000 Teamsters, and has added 40,000 union members since its current contract was reached five years ago. UPS (UPS) began offering regular Saturday delivery service just a year ago. Typically union members remain on the job until a new labor deal is reached. The last time UPS had a strike was a 16-day walkout by the Teamsters in 1997, and there hasn't been a bigger strike since then.
