There is already a track record.
If Obama is re-elected, Wal-Mart could be unionized in much of the country before his second term is out. The NLRB’s Boeing-South Carolina decision indicates a willingness to prohibit Wal-Mart’s standard defenses, and their response to successful votes, which has been to close the offending store or department.
At a certain point, Wal-Mart will capitulate. Better to strike a national deal with the UFCW that it’s competitors will struggle to beat, than run the risk of fighting it out and being forced to run hundreds of stores unprofitably.
