Due to upcoming budget cuts in 2019, the NLRB is drawing out a plan to scale back it’s size and scope in the near future. According to General Counsel Peter Robb, the board has between 70 to 100 excess full-time employees that were never approved by Congress. Robb plans to minimize operations in field offices across the country, inevitably leading to a steady decline in cases that the board will handle in the coming months and years.
