Vantaggi
I have worked for SAIC/Leidos for over 15 years and I can't say there are any longer many things to be proud of with this company. What used to be a very good team environment where everyone worked together to succeed has been replaced by a "each person for themselves" attitude that is very disheartening.
Svantaggi
Upper management is horrible. There lack of communication or poor communication has created the work environment noted above. Few if any employees feel that their performance matters much. If you bust your butt and work hard you are looked at well while there is work but the minute a project ends you are dumped without so much as "how do you do". The feeling you are left with is your efforts mean nothing in the long run and everyone is "Out for themselves"
