In Japan, legal protections concerning retirement conditions are not very strong. Negotiating an increase in the retirement package through a union is challenging. If the explanation of the MSA (Mutual Separation Agreement) is illegal and coercive, and as a result, you suffer financial or mental harm, depending on the details, we can assist you in filing a lawsuit and seeking compensation. However, in many cases, the amount may not be substantial. Even if you do not intend to continue working at the company, if you are unsatisfied with the amount of the retirement package, it is recommended that you decline the MSA, stay with the company, and then resign voluntarily at a timing that is convenient and satisfactory for you.
