Once an employee or former employee files a charge, the EEOC then conducts an investigation. The EEOC does not have the resources to conduct full-blown investigations in every case. They often focus on charges the agency thinks are particularly egregious or those in which a broad class of employees are involved (class action suits). The EEOC will perform some level of investigation, which can include interviewing witnesses, visiting employer sites, requesting employment documents and other actions. The EEOC will then tell its findings to both the charging party and the employer.
