The impact of this executive order will be that anyone not belonging to a union will be unable to bid on federal contracts. Ultimately, if you don't belong to a union you will not be able to find a job or work for any company that does business with the government. What Obama has done with this executive order is to "kill" all non-union companies or relegate them to jobs not associated with the government. This puts union companies in the driver's seat on virtually all of the big-ticket contracts in the country and destroys any and all non-union competition. So, he got one better than "card-check." He got "Card-Mandate."
