The National  Retail Federation released a new report just over a week ago that predicts that new overtime regulations being proposed by the Obama administration will result in significant increases in costs to businesses across the country, but will have the greatest impact on the retail industry.  The NRF report, conducted by Oxford Economics, found that 81 percent of restaurant and retail managers are opposed to increasing the overtime exemption threshold and 75 percent of them believe the proposed changes would diminish the effectiveness of employee training.  The current threshold is $455/week, while the Obama administration is looking at increasing that amount to something between $610 and $984.
