Pros
Honestly for some LM is a fantastic place to work. If they have work for you and you have a good manager you will probably come into work with enough to get you through the week and excited to come back on Monday. The 4/10s have their pros and cons but personally it is great to have Fridays to relax by myself. Luckily there are so many people on campus you are bound to find a few friends.
Cons
I have worked at LM Space in Co, LM Aero Palmdale and Fort Worth; and Fort Worth has undoubtedly the biggest ego. They are still and will forever be General Dynamics the designers of the late great F16 and (eventhough it was LM’s) F35. The company boasts a metric that says 50% of employees are within 0-5 with the company which is not a good metric to talk about. They have a serious issue with most groups having most people with all of the work within 5 years of retiring, then one person who is in the gap range (30-50) and a bunch of new hires who they are looking to have absorb all of the retirees knowledge in 5 years.
