Car haulers were authorized to return to work.

The rare action by the Teamsters Union allows more than 20,000 striking car haulers and yard workers to go back to work Sunday, ahead of actual rank-and-file ratification of their new three-year contract. Detroit auto makers, who along with foreign car makers suffered from clogged inventory lines during the three-week strike, expressed pleasure with the news. Although union local leaders approved the new pact Friday, the membership votes probably will not be counted until mid-September.
