The United Steelworkers union (USW) said little progress was made in talks with oil companies on Tuesday for a new U.S. refinery workers contract as a strike at 11 plants completed its 10th day, according to a text message issued by the union. The USW said lead oil company negotiator Royal Dutch Shell Plc failed to bring experts and information as promised when talks ended last week. A Shell spokeswoman said on Tuesday night that the firm was working “in a good faith effort to collect the requested data”.
