I also haven’t had any experience in a non-welcoming culture myself. I saw a struggle of another Engineer who was shy, quiet and couldn’t make his point. Based on my assumptions the non-welcoming might happen more often in smaller companies with low benefits were people are just unhappy. They pass their frustration on others. I also noticed that some older people have hard times of listening to new younger bosses. I believe that organizational culture plays important role in the work environment. Employees are more motivated when they enjoy coming to the work.

Thanks
