I have it on good authority that they are working with a management consulting firm to revise the severance package policy. They won't change the 2 weeks of pay per year of service, however it won't start increasing until year 5. This is due to the 60 day notice period. Everyone at 4 years or less will get 2 months of severance, regardless of tenure before accumulating more starting on year 5.
Essentially what they're doing is eliminating the overlap with the 60 day notice.
