Is there any reason not to take the buyout?

The fact that you will be jobless in this economy.

I can’t think of many companies that would be better to work for than Microsoft in terms of compensation.

It's 9 months. They probably won't do layoffs again for 6 months and you will get a package then for more than 3 months. Makes sense to hang on.

In this sort of situation, always take the first offer. Subsequent offers are always worse.

Traditional if you know you’re a shitty employee that can’t find a new job you stay.

Voluntary packages tend to be accepted by the strongest employees

It’s a shitty deal for companies but shareholders love cost cutting

no job?

if you prefer being fired!
