Historically employers could not restrict labor organizing activity in employer-owned, publicly accessible spaces. But, last month, in UPMC Presbyterian Hospital, 368 N.L.R.B. No. 2 (2019), the NLRB reversed nearly 40 years of precedent holding that employers violate the National Labor Relations Act (NLRA) if they prohibit nonemployee labor organizers from publicly-accessible spaces.
Post UPMC, employers may adopt and implement neutral policies regulating the use of employer-owned spaces open to the public (such as cafeterias) and may lawfully apply those policies to exclude nonemployee union organizers. Employers with spaces open to the public should consider whether to adopt and enforce a content neutral (nondiscriminatory) bar to nonemployee solicitation or distribution in the publicly accessible spaces on their property.
