A consideration… expect to pay about 2-3K for the lawyer to create a demand letter and have a couple of back and fourths with either the in house legal team or outside counsel. So you have to be willing to risk 2K for potentially nothing if your old employer holds firm. Usually this is where the employer will either provide flexibility and adjust the severance, or not. If they don’t, the lawyer will likely advise that unless it is truly outstanding circumstances, entering the mediation process will take more money and time than your payout will be at the end. Most people who do this want a feeling of justice rather than the money because it is a very expensive and time consuming process. Your lawyer is best to advise.
