Right now, it can be reported by a former employee up to three months after the occurrence. Then there is one year for the employer to figure out whether they can resolve it through informal discussions or the conciliation process, or whether there's an investigation process. There are multiple ways for the employer to resolve it. One year is given for that. After that one year, the employee can again take another three months to make a formal complaint if they have not been satisfied by the employer.
In total, I would say that it's 18 months under the current law.
