REUTERS/Erwin Seba HOUSTON, June 25 (Reuters) - No new proposals for ending a two-month lockout of 650 United Steelworkers union members from Exxon Mobil Corpâs (XOM.N) Beaumont, Texas refinery were made during a meeting this week, said union and company spokespeople. The lead negotiators for both sides met on Wednesday, but no proposals were exchanged, the spokespeople said. Exxon locked out the workers on May 1 citing the risk of a strike. The USW has said the companyâs last proposal requires its members to give up long-standing seniority and would create a separate contract for workers in a lube oil plant from that for workers in the refinery.
