Creates the Warehouse Worker Protection Act. Requires each employer to provide to each worker, upon hire or within 30 days after the effective date of the Act, whichever is later, a written description of each quota to which the worker is subject, including the quantified number of tasks to be performed or materials to be produced or handled within the defined time period, and any potential adverse employment action that could result from failure to meet the quota. Provides that a worker shall not be required to meet a quota that prevents compliance with meal or rest periods or use of bathroom facilities, including reasonable travel time to and from bathroom facilities. Requires employers to post a notice of workers' rights under the Act and to comply with certain recordkeeping requirements. Sets forth a rebuttable presumption of unlawful retaliation if an employer takes an adverse employment action against a worker within 90 days of the worker requesting certain information or making a complaint alleging a violation of the Act to the Director of Labor, the Department of Labor, or the employer. Sets forth provisions concerning definitions; enforcement of the Act by the Department; civil penalties; workplace inspections; private rights of action; the Attorney General's powers to intervene or initiate a civil action; and severability.
