Under 1977.17 (Withdrawal of complaint), can an employee unilaterally stop OSHA's investigation by asking to withdraw their complaint?
No — an employee's request to withdraw a complaint does not automatically stop OSHA's investigation. The regulation explains that the Secretary's jurisdiction cannot be foreclosed by the employee's unilateral action, although a voluntary, uncoerced request will be given careful consideration and substantial weight. See 1977.17 and the broader 1977 part page.
