Sorry about not addressing that.
Severance is a tricky issue because no law requires the payment of severance in any amount, except in certain very limited circumstances involving mass layoffs at large companies on short notice. Employers are generally motivated to offer severance in exchange for a waiver of any legal rights the employee may have to sue. Naturally, therefore, the amount of severance offered tends to correlate to the "litigation risk" the employer believes the employee presents. For instance, if the employee is being "laid off" shortly after complaning about sexual harassment, the employer would likely assess a large exposure, as it could be alleged the layoff is really a retaliatory termination. In that case, they would offer a large severance package.
But the thing is, most employees don't have a basis to sue when they are let go. This is because employment is "at will" absent an agreement to the contrary. So, it is difficult to negotiate severance because they really don't have much leverage to be making demands.
The customary rule of thumb when the employee does not present a significant "litigation risk" is 1-2 weeks severance per year of employment. One year's severance would be very large, and likely not to be expected unless you have been working for this employer for 20+ years.
I hope this clarifies. Again, please feel free to let me know if you have any further concerns. If I have answered your question, I would be very grateful for a positive rating of my service so that I may receive credit for assisting you.
