      Pros

      CertainTeed is a very large company

      Cons

      Highly toxic place to work. No structure; no systems; no standards. There are no opportunities for growth. It is very difficult to improve anything or complete projects. Very unprofessional. Poor and uncomfortable office environment - unclean washrooms and all.
