Which statement is INCORRECT about the National Labor Relations Act?

The NLRA was enacted because the judicial branch had been extremely in favor of labor movements

throughout the history of the country until $1930$s$.$

The law intends to facilitate negotiations for collective bargaining between employers and labor unions.

Since the federal law does not cover public employees, workers hired by state governments must follow

state labor union laws.

Labor unions cannot intentionally discriminate their union members in collective bargaining process and

other representation matters.
