Pros
I am blessed to be a part of an incredible team. We are a team in the true sense of the word. I feel my manager and my manager's manager truly care about me and my career goals and do their best to expand and grow my skills. I feel very cared for. While there has been a great deal of change during the 10 years I have been with Leidos, I would not want to work for anyone else. Great compensation. Terrific work/life balance. Very focused on ethics.
Cons
As mentioned above, there has been quite a bit of change at Leidos over the years (new CEO's, splitting of SAIC into two companies). That has created a feeling of instability at times, and there has been some frustration over changing benefits and streamlining of processes. This is probably fairly normal, as all companies must go through changes, but I get the feeling many employees are stressed and morale is lower than it should be.
