Pros
Benefits are not bad as long as you are not under the SCA contract. Health insurance choices for employees outside of the SCA contract are nice and provide quite a few options from which you can pick to meet your needs. The mobility program allows an employee who is at-risk to look for another job within the company minimizing your time as an unemployed worker. ManTech hires a diverse group of people which makes a person feel valuable, especially, if you are one of the individuals who falls under a minority category. ManTech likes to hire former military personnel which enables former military members to transition to the private sector.
Cons
Contract-centric company which means that if the contract is going away your job is gone. Management is very much the good-ole-boy network, if you are not part of the in-crowd, you are part of the out-crowd which means you will be cut to ensure that an in-crowd person retains their job.
