When it comes to labor regulations, businesses are dealing with multiple levels of uncertainty.

Speaking at an event yesterday hosted by American Action Network and Crossroads GPS, Chamber Senior Vice President of Labor, Immigration, and Employee Benefits Randy Johnson took issue with a proposed National Labor Relations Board (NLRB) rule to help unions create gerrymandered bargaining units, which would force businesses to negotiate with multiple micro-unions. Complicating matters is the fact that NLRB rules issued by the current group of commissioners could eventually be struck down if courts rule that President Obama's recent recess appointments to the NLRB are unconstitutional.

This was something the President "could have avoided," said Johnson. Manhattan Institute Economist Diana Furchtgott-Roth added that "businesses will be in limbo" until the judiciary settles the controversy. Today, the House Judiciary Committee is holding the third congressional hearing this year to examine the constitutionally of these questionable appointments.

Johnson, citing a recent U.S. Chamber survey, noted that 49% of small businesses say that regulation is a greater threat than taxation and litigation and that nine out of ten say that regulations have a negative impact on their businesses. Survey respondents also said that the 2012 health care law makes it harder for them to hire workers.
