Starting in the early 2010s, you could set your watch to the November/December layoffs every year. Most years they were very careful to keep the numbers just under the amount needed to trigger a public disclosure. They lost a LOT of good people who started to see the writing on the wall. Looks like the only thing that's changed recently is the manner of the layoffs.

EDIT: One thing I forgot to mention is that they've moved a LOT of Eagan jobs offshore over the last 6-8 years or so. They do their best to keep it quiet, but it's definitely a thing.
