Idera bought out a company that I used to work for. They immediately let half of the workforce go without compensation. They are normally (in Canada) expected to pay severance, but an extremely optimistic interpretation of our employment contracts led them to believe that they could let us go and pay severance to anyone who was still unemployed some lengthy time (If I remember correctly, about 9 months) later. They are the Gordon Gekkos of the software world and I wish them absolutely no success. If you get bought out by them, lawyer up and start searching for a job immediately. If a product that you use is acquired by them, then start shopping for an alternative.
