Is that employee autistic? One of the things that management requires is learning to communicate with all types of people and help others communicate. After all, your job isn't producing something, it's making sure your employees that do the actual work are able to do their job effectively.
I'm just using autism as an example because I happen to be on the spectrum, though I've learned to mask well over the years. Autism has tons of advantages in the way we think. Great at analysis, great at handling emergencies, etc., but our communication style is a little different. We tend to need communication to be direct and precise because we analyze things too much sometimes. Problem is that because we're so used to being misunderstood or misunderstanding people and getting into trouble for it and being scolded for asking clarifying questions because we "should just know what they meant", that we often don't ask the questions and try to interpret things in all the possible ways.
And maybe it's not even at this job that they were scolded, they just are used to neurotypical people scolding them for the way they think, that they no longer even try to ask questions. So my advice is to make sure the person is not only able to ask questions, but is encouraged to do so if they need to. Make sure to be very positive when they do and make sure the other people they interact with are positive as well. It's a very small accommodation that could help them thrive and end up being one of your best employees if given the right atmosphere.
Again, I'm using autism as an example because it's a commonly misunderstood condition that is not a disease and not curable, nor should anyone try to cure it, it is just a different way of thinking and is a spectrum of various types of ways of thinking that people are often forced to mask and so is commonly undiagnosed or misdiagnosed. Heck, I didn't figure it out until a few years ago and I'm in my mid-40s. But it took me decades to learn to effectively communicate without knowing why some people just couldn't get me. Even now I tend to over-communicate as you can see from this wall of text.
But as a manager you should try to get to know your employees' strengths and weaknesses, communication styles, etc., and help them to communicate more effectively with each other. It has helped me to be effective at coordinating people.
