The General Counsel for the National Labor Relations Board issued a Memorandum that states that nine standard employer policies will now be presumed lawful under the National Labor Relations Act. The new Memorandum provides a guide for employers to defend their commonplace rules, which faced severe attacks under the Obama NLRB.

The Memorandum is based on the NLRB's decision in The Boeing Company issued in December 2017. Previously the NLRB had taken the position that these policies were unlawful because they could have a "chilling effect" on employees' exercise of their rights to engage in "protected concerted activity" under Section 7 of the NLRA.

The Memorandum is GC 18-04 which can be reviewed here:
