Final answer:
An investigation into an EO complaint should generally commence within 72 hours of the complaint submission. This timeline can vary based on the specific institution or jurisdiction, but 72 hours is a standard for federal and military EO complaints.
Step-by-step explanation:
When an Equal Opportunity (EO) complaint is submitted, the investigation process is subject to strict timelines as mandated by regulations. The specific timeline for commencing an investigation can vary based on the institution or organization, as well as the jurisdiction in which the complaint is made. Generally, for most federal and military processes, an investigation should begin within 72 hours after an EO complaint is filed. This ensures a prompt response and the protection of all parties' rights. It's essential for those involved in an EO complaint process to be familiar with the relevant policies and procedures to ensure compliance with all legal requirements.
