If things go like they have in the past, NOBODY will be laid-off. At least no engineers that is. QCOM does not lay off engineers. They fire them. Seen it happen several times. The quota comes down, management is forced to "identify" x% of the department that is not performing to expectations. A letter of expectations goes out. Then a PIP starts. The employee is then generally given the choice of completing the PIP or accepting what everyone seems to be calling the "lay-off package." Generally 3 months of pay for a resignation. I saw one guy negotiate to 4 months. I've also seen people who's review feedback was coming in at "exceeds expectations" be fired. It doesn't matter what your co-workers think of you. Just what you supervisor and his/her peers think of you.
An actual work force reduction (lay-off) has rules, including loss or reduced quota of H1B visas and inability to hire engineers to replace the position(s) eliminated for some amount of time. All hiring in my department over the last couple of years has been new college grads. We hire lower cost engineers (~80% via the H1B visa) and fire the lowest performing experienced engineers. Unfortunately we've already fired the true low performers. Now we just fire the ones at the bottom of the curve. .
So if you're an engineer, don't worry about being laid-off. Just worry about being fired. Don't be towards the bottom of the performance curve. Kiss the ass of your boss. This is survival of the fittest. Are you willing to sacrifice personal life for your job? Many people are. Working 60 hours per week is not enough in itself. You have to be productive as well. But all things being equal, the person working 60 hours per week is going to win.
The younger engineers (unmarried, not home owners) are already leaving for greener pastures. If you have skills and don't mind leaving San Diego, and aren't getting really good reviews, I suggest you start looking. Even of you are getting good reviews, you might want to start looking because the greater productivity that management is creating is on your back. Less people, but not less work means we become more and more of a sweat shop.
QCOM is simply becoming more like the average high tech company. Engineering is a tough field. Lay-offs are very common. QCOM is the only company I've ever worked in that gave engineers actual offices rather than cubicles. Stock options, RSUs and bonuses we unheard of in two of the companies I worked at. I shared a cubicle in my first job out of college. If you've never worked anywhere else, you're spoiled.
By the way, directors are not immune to cuts. I saw one of them get axed too.
