Companies will try to avoid hiring older workers.
While older workers may be more experienced, two things work against them. First, is that companies can generally get away with paying younger workers less money. Secondly, older workers in group insurance plans will cost the company much more in insurance premiums. So pay and benefits for older workers will cost the company money.
Another factor depends on the job. But for all but senior management type positions, the fact that someone has 20 or 30 years of experience in some field does not impress employers. If they can hire a 35 year old with a degree in a certain field and five years of experience, that’s just as good to them as a 50 year old with 25 years experience. And the younger worker will cost them less money, so the bias is towards hiring younger workers.
