The National Labor Relations Board announced Tuesday it will allow voting in a union decertification election to continue as it considers whether to apply a union contract doctrine to the election proposed by a Delaware poultry worker.

The board will consider whether about 800 employees at Selbyville-based Mountaire Farms Inc., represented for collective bargaining purposes by employee Oscar Cruz Sosa, are allowed under contract to vote to decertify from the United Food and and Commercial Workers Local 27 union.
