In an economy where general unemployment is 8%, I'd say the incremental job-loss risk at E-Trade over PMC is higher than 4.76%, so better expected value to stay at PMC.
To be fair and make this decision model more robust, you need to also account for
1) the potential earnings upside at E-Trade over PMC, and
2) the present value of the incremental earnings upside over 20-30 years.
So for example, assuming the incremental risk of job loss at E-Trade is exactly 4.76%, then the insurance premium of $2.5k you pay (forgone higher earnings) for job security at PMC is priced fairly. However, that's only half the equation (downside).
You also need to look at the probability of higher upside at E-Trade. So if there was a 50% chance you could make $10k more per year at E-Trade, you have positive expectancy of $5k per year, which depending on your personal utility curve may or may not make the difference. But then you also have to take the present value (PV) of this incremental $5k annual expected value over 20-30 years (your remaining career), which at 3% interest equals approx $75k-$100k (look up the formula for PV). Again, you'd need to adjust these expected values for job loss risk. It sounds complicated, but pretty straightforward if you get the concepts right. Remember to keep units on apples-to-apples basis.
To simplify all this, if the gross earnings differential is just $5k per year, then not worth the additional risk of job loss and incremental commuting cost. Plus you get quality of life improvements. However, if you could see your annual earnings realistically growing by more than $10k per year over the long run with low incremental job-loss risk, then it would make sense to take the E-Trade job.
