Salary is not commensurate with industry. We are told that since we can say we "work for MIT", our salary is less than what outside non-FFRDCs offer. There is no training for managers. Most are former technical types or engineers that have zero management experience and not competent at all in that area. I have refused to forward any resumes to HR and have told very talented people that I would not recommend MIT/LL to them so I will not submit their resume for employment. There are plenty of other work places that will provide a more satisfactory job experience.
Very expensive health insurance if you don't live in the MIT area. Average monthly bill is $700 for familly health insurance with fairly large deductibles. If you work at a field site, you essentially have to subsidise your own health plan. If you can use the MIT clinic, it is great.
