I really enjoy my work and it is rewarding to me that my job is important.

…I initially wanted to join the company because I liked the location. When I walked in the door I was greeted pleasantly. I had a good experience with Human Resources and I really like my supervisor. After I received an explanation of what the company does I felt it would be a really interesting business…

There are so many things I enjoy – the people, management, everybody is nice and helps other people. It is a great atmosphere. The workplace is also very clean. I really enjoy my work and it is rewarding to me that my job is important. I’m doing work for the army and I must do it right! It is special that they use what I make. I’m growing because everyday I learn something new. Anybody who wouldn’t want to work here is foolish. We have fun and that makes it good for everyone…
