HOUSTON—Exxon Mobil Corp. on Wednesday offered its first concession in a new contract proposal to locked-out workers at its Beaumont, Texas, refinery and lube oil plant to include some seniority protection.
Exxon on May 1 locked some 650 workers out at the 369,000-barrel-per-day refinery, replacing them with temporary workers and saying the company was afraid a strike might lead to disruptions to production.
