That's because it is. Maybe if you are a mgr. or director and are young enough to make AZ a long career (good luck with that), then maybe the stock option thing may make sense. DSM's I think get 13% of their salary. The higher the rank, the higher the percentage. Remember, three years to vest.
Why would you walk away from an additional 6-8% 401K match that is vested right away?
The company knows this. Eventually, they will force everyone onto the new plan, just like they did with the old defined pensions. Could be a couple of years, could be 10. Don't know the time just that it will happen.
