On a strategic level, employers really are behaving stupidly. Look at how they do recruiting: this automated process under which they will publish a job description chock full of so-called "key words", and then have software algorithms that attempt to match applicants to the resumes against those key words. So where in the key word collection do we capture institutional knowledge? No one advertises for that. Of course they don't.

There is age discrimination, but I think there are two kinds. One is when the employer is discriminating for specific reasons and doing it intentionally. The other is where you have managers who really aren't looking to discriminate but feel a little on edge because the candidate they're talking to is older. Sometimes they can even smell age concern on the part of the candidate and they wind up discriminating almost unconsciously.

When you're not recruiting effectively you're not recruiting properly through a certain channel, like a job board, then what's left of you? I don't believe HR's been able to figure that out. They need to go back to the way they used to do it. They complained that they got so many millions of applicants, they couldn't possibly spend the amount of human time on all those applicants. But they could solve the problem tomorrow if they stopped soliciting millions of applicants through job boards.

I think what's happening is companies are trying to maximize shareholder value and I think they realized that if they could hire more effectively, they would. What I'm suggesting, though, is that human resources departments in most companies have become so detached - have become such a bureaucracy - that they have become clueless. They don't realize that the processes they have put in place have very little to do with recruiting, retaining and bringing on talent.

Remember, the word "discrimination" isn't always pejorative. When an employer discriminates because an older worker lacks certain kinds of skills that are important in the market today, then it's almost a legitimate form of discrimination because the employer is just trying to figure out who can actually get the job done.

I think stupidity in business is really an interesting thing. What winds up happening is a disconnect between your company's strategic management and then your more applied on-the-street management. I guarantee with you that the board of directors of most companies has no idea what the costs of hiring people really is in the HR department.

Sure, some employers are are afraid of letting older workers go because they think they're going to get sued. And they probably will get sued. But the reality is, you could get sued at any time by any kind of worker. I think its incumbent on an employer, if they want to be smart, to figure out what is the benefit of keeping this employee or letting them go. Do the calculation and just go ahead and either keep them or let them go based on what's good for the business.
