The pay for performance structure seems to be slightly broken, and during uncertain times it is very difficult to get a promotion, even if you exceed all of the requirements. Additionally, a large portion of the developers in the company are being moved to a services pay ledger which will pretty much freeze any pay increases that you were expecting in the next 5 years.
ELDP has been significantly modified, so it is not nearly as attractive as it was before. For example, when I started my master's degree Lockheed agreed that they would pay for the full degree as long as I worked for them at least a year after the degree. 1 year into my masters degree they changed this requirement to 2 years. Additionally, when I first started at Lockheed their health insurance was quite affordable, in my 5 years it has gone up over 400%. My yearly pay raises barely make up for these increases.
