If your employees are idiots, you're the one to blame

​I stumbled on this interesting article on leadership and low-performing direct reports:

The first problem of course is thinking that one of your people is an idiot. Once one of your people knows your low opinion of them they are unlikely to exceed your low expectations. Never ask or expect less from your people than you need or want them to deliver.
If you’ve hired someone and they are not getting the job done there are only two possibilities.
You’re not going to like either one.
The first one is that you simply hired the wrong person. Yes, you simply hired the wrong person. If they truly cannot get the job done then why did you hire them? If they didn’t have the skills, knowledge, and experience to successfully complete the requirements of their role then why in the world did you hire them? You must have just hired the wrong person.
The second possibility is that you did hire the right person but you’re not giving them the tools they need to succeed. You, as a leader may not be teaching them the additional skills required to truly excel. Your may not be transferring your additional knowledge and experience to them.
Either way, if you’ve hired someone who is not succeeding it’s your responsibility. When you accept 100% responsibility for the success of your people you begin to grow as a leader.
When you accept 100% responsibility for the success of the people you’ve hired you’ll no longer be so quick to dismiss them with a “they’re an idiot” flick of your tongue. You will stop “spending time on” and start “investing time with” your people.
