NLRA applies to all employers in interstate commerce, but for administrative purposes, the NLRB has limited NLRA coverage in the non-retail field to those employers whose gross volume in interstate commerce is at least $50,000 per year. For other sectors of the economy, the standard is based on yearly gross volume and may vary from as little as $50,000 to as much as $1 million, depending upon the industry. The Act guarantees employees the right to engage in “concerted activity” for mutual aid or protection. These activities are protected under the law:
• The attempt by one employee to solicit union support from another employee
• Discussion of unionization among employees
NLRA further requires management to recognize unions that represent a majority of their employees. It also provides a system for conducting elections to determine who represents the employees, and procedures for adjudicating unfair practice charges.
