This is a terrible mindset to have. When I was a manager I took every opportunity to praise my employees (with meaningful compliments and feedback) and discouraged negativity. During a management team meeting I even stood against the others on promoting someone because he was always negative and I pointed out how inefficient his coworkers were around him and that he would only continue that, it didn't matter how good he was himself at the job, he needed to be encouraged to change for the better. After working with him for a while and helping him see how he was hurting others and himself, he changed his mindset, and was later promoted, I continued to coach him even after I left that location.

My basic point is this, even those with the wrong mindset can be swayed with the right mindset, as long as it is sincere.
