Hi Nate! I don't have an answer to your post. So, I should probably shut up, right?
I don't know if people (in general) just don't have sense enough to recognize their own bias on this topic, but I know no one is going to publicly admit to discriminating based on age. People interviewing an older person MAY think:
1. This person is going to retire in a couple of years and then I'll have to go through this whole process again. Ugh.
2. This person already has a pension he/she is collecting and doesn't really NEED this job. I should offer it to someone younger who doesn't have that security.
3. This person will not be healthy and will miss a lot of days (As if older people are sicker more than young ones.)
4. What happens if I hire this person and no one will listen because he/she is set in his/her ways and won't be able to lead or motivate this new generation?
5. Can this person learn new software? Can this person adapt to OUR way of doing things?
None of the above is true, of course, of most workers, let alone the older workforce. But I can imagine someone who is already in a corporate position at the age of twenty-five to thirty may still buy into that thought process. After all, their parents may be experiencing a decline in health or energy or may be closed-minded to new ways of thinking, so they assume all older people are like that, too. I also think (and this is probably just me) that the younger Supervisors who are high achieving may wonder why someone who is 50-65 would even want to take a position as a lower level manager or in maintenance as a tech or turn-key tech (speaking for this industry only.) I can also understand someone who is looking to hire a leasing agent who would have an idea in mind of someone who will fit in with their demographic (say, a Student Property) and immediately rule out anyone over thirty!
So, nope, I can I can't make any definitive assumptions, but I can see this happening.
