The approval follows a meeting in Detroit on Friday morning of the union's local leaders at which the details of the proposed labor agreement with GM were unveiled.
GM and UAW reached a deal early on Wednesday, ending a two-day national strike by GM's UAW-represented workers. The tentative deal needs to be ratified by a majority of the automaker's 73,000 workers.
" I think everyone should approve it," said Terry Frederick of UAW Local 14 in Toledo, Ohio, as he left the meeting.
UAW President Ron Gettelfinger told reporters on Friday that the union will resume negotiations with Ford Motor Co and Chrysler LLC next week.
The UAW had extended its previous contract with both Ford and Chrysler to focus on bargaining with GM.
Gettelfinger said the proposed contract with GM would allow the automaker to hire new workers for " noncore" work at lower wages and make way for about 3,000 temporary GM workers to be made permanent.
The UAW and GM had so far not provided any details on the deal, except to confirm that the automaker would be shifting more than $50 billion of retiree health-care liabilities to an independent union-aligned trust -- a breakthrough expected to allow Detroit automakers to cut in half the labor-cost gap with their Japanese rivals.
The contract also includes a $3,000 signing bonus and a new round of buyout offers for GM workers, a person briefed on the details of the contract said.
