" If your considered management, then its based on your level, 1a, 1b, 2, etc as to buyout."
First, it's if "you're" considered management.
Second, you're incorrect.
Third, there are no "buyouts". What's a buyout?
Management (non bargained) severance is not based on level. It's paid according to the management severance plan, which can be reviewed on HR One Stop. It's maxes out at 50% salary for those with 13 or more years, and goes down from there for those with less.
