Bosses that take credit for everything you do. You will get absolutely no recognition at Pilz. They will squeeze everything they can out of you and then get rid of you. They are an "at will employer", meaning they can get rid of you for any reason. Pilz's compedators will likely put them out of business within the next few years. DO NOT work here if you have a family because one day you may not have the means to support them.
