"Except where there is a threat of imminent danger, employees are required to provide 'appropriate notice' of their need for leave. While the statute does not specifically define 'appropriate notice,' employers should use the same notice period required in their other leave policies. This notice may be communicated by either the employee or another person acting on the employee's behalf. If an unscheduled absence occurs, an employer may not take any negative action against the employee if the employee produces documentation within 30 days."
