WASHINGTON (Reuters) -Evidence submitted by a retail union that raised objections to Amazon.com Inc's conduct at this month's union election in Alabama "could be grounds for overturning the vote", the National Labor Relations Board said on Wednesday.

The labor board has overturned several union elections over the years. In 2016, the board overturned an election the United Steelworks union lost by a decisive vote - a decision criticized by large U.S. business lobbies.
