The NLRB has delivered an opinion changing its policy on arbitration agreements, tightening the standards under which it will evaluate the findings of an arbitrator over unfair labor practices before deferring to those findings. The burden of showing why a court should agree to an arbitrator’s standard has now also shifted to the party favoring deferral. Under the board’s new standard, deference to an arbitration award involving an unfair labor practice is appropriate when: “(1) the arbitrator was explicitly authorized to decide the unfair labor practice issue; (2) the arbitrator was presented with and considered the statutory issue, or was prevented from doing so by the party opposing deferral; and (3) Board law reasonably permits the award.” The case is Babcock & Wilcox Construction Co., Inc. and Coletta Kim Beneli (Case 28-CA-022625), and the decision is available in its entirety here.

Two national hotel-industry groups have filed a suit against the city of Los Angeles, challenging a recent minimum-wage increase as a violation of federal labor law. The Hotel Workers Act, which is slated to take effect in July, would have raised minimum wage in large hotels to $15.37/hour. The groups filing suit –  the American Hotel & Lodging Association and the Asian American Hotel Owners Association – argue the Act unfairly targets a single industry. The groups further claim that their concern is not the wage increase, but a provision of the act allowing its requirements to be waived by any hotel covered by a collective-bargaining agreement. In doing so, the group argues, the law allows unions to pressure non-unionized hotels to organize. The Wall Street Journal reports.
