First fork
Identify the worker and respondent before choosing a filing system.
The Equal Employment Opportunity Commission does not use one universal path for every workplace problem.
Start with the legal employer shown on pay records, tax forms, the offer letter, or personnel notices. Then identify any staffing company, worksite company, parent, affiliate, union, employment agency, government department, or contractor involved. A trade name, supervisor's employer, or worksite sign may not identify every proper respondent. Coverage and joint-employer questions require facts about control and the governing statute.
Private-sector and state or local government workers generally use the EEOC charge system for laws the Commission enforces. Federal employees and applicants normally begin with the employing agency's Equal Employment Opportunity counselor and follow a separate federal-sector procedure. A union member may also have a grievance path; protected concerted activity may involve the National Labor Relations Board. Leave issues may involve the Wage and Hour Division; and Oklahoma discrimination complaints may involve the Office of Civil Rights Enforcement.
Do not assume filing in one system completes another. Worksharing or dual-filing arrangements can matter, but the actual charge, agencies named, acceptance date, protected bases, and notices control. Preserve every confirmation and ask whether a separate state, federal-sector, labor, safety, benefit, contract, or court step is required.
