Age Discrimination

This Tuesday we had a guest speaker again. Although the presentation was quite rushed, the topic she chose was quite interesting. We discussed how age discrimination is a huge issue in workplaces today. She showed us a video where an older man had two separate interviews at the same business, one wearing makeup as an older man and the other as himself, a younger man. It was interesting to see how the interviewers were very stereotypical. The interviewers in the end chose the younger man because they figured that he would stay with the job longer. I guess it is proven that older people switch jobs more often. I found this strange because I would think that a young adult is more likely to switch jobs because they have more opportunities. I also would think the younger man would be less likely to get the job because they would seem less responsible. They have less responsibilities are typically do not have a family.
This issue was also interested me because my father is dealing with a situation similar to this. He was the senior salesman in his work, and made the most sales out of anyone there. He also had been there for almost 11 years. The company had recently hired a new manager, and he wanted to create a new "change". It was found that this change was new, younger employees. My dad, along with several other senior sales reps were fired. My father along with the others are currently suing the company.
In the end, I leave off with the question... who do you think deals with more age discrimination in the workforce, younger or older prospects?
