For most of the 2000s, the National Labor Relations Board(NLRB) reviewed facially neutral work rules under an employee-friendly standard, leaving companies worried that employees could construe neutral rules to interfere with protected activities under Section 7 of the National Labor Relations Act (NLRA). However, in December 2017, the NLRB overruled the employee-friendly standard and established a new balancing test in The Boeing Company, 365 NLRB No. 154 (Dec. 14, 2017), and created three categories of work rules.
