Loads of comments already, but here goes. My brother used to work for Big-DoD. He quit, for reasons you explain here. But, he did tell me about a time his perspective was changed.
He decided to stay late in the cube farm. His original idea was to go around to all the cubes and count to number of Dilbert Cartoons stapled to the oatmeal gray walls. he thought this would be evidence that everyone was cynical and full of shit. Ok, so, her grabs a post-it and goes about tallying it all up.
What he saw was not Dilbert and black humor but desperate passion. Most of the cubes were not messy, they were not cynical, they were not reflections of the company.
He showed me that ~85% of the cubes were more or less shrines to their families. Pictures of rosy cheeked little girls on swings, little boys with trucks and sticks, graduation photos, school flags and colors, game schedules and rehearsal dates, church functions, pictures of wives on beaches, men dancing the tango, wedding photos with really bad hair-dos, parents with liver spots and tubes in their noses, etc. Most of the cubes were just covered in pictures of family, just every inch.
Ok, got it? Most people at this company didn't give a flying turd about the missions or the day to day. They all knew it was some load of horse hockey. It was their families they really cared for. They went in day after day only for those kinky haired girls and those octogenarians. To give their families a better shot at life, to go to college and make a difference.
The plant shut down about 5 months ago, leaving all those there in a hell of a lurch.
Honestly, I don't know what the take away is here. That you should work harder, or that families are toxic to a company, or that they weren't dedicated enough to their families. I don't know.
But the people that you work with are just that, people. Forgive them. Love them too.
