Hi again. Thanks for your patience while I was assisting other customers.
The employer must follow any employment agreement that it entered into with the employees. Accordingly, if there is an employment agreement which states that a specific amount of time must be given to negotiate severance agreements, then the employer must abide by it. The employees could sue the employer if the employment agreement is ignored.
However, if there is no employment agreement, then the employer doesn't have to provide any particular amount of time to negotiate severance agreements. In fact, the law does not even require the employer to provide severance agreements. Accordingly, in that situation where there is no employment agreement covering this scenario, I'd take whatever I could get from the employer if I were in your son's shoes.
So, the bot***** *****ne is that your son's recourse depends upon the specific facts in this case, such as whether there is an employment agreement that covers this scenario.
Does that answer your question? Please let me know if you need clarification, as I am happy to continue helping you until you are satisfied.
