Is this sentence OK?

My colleague is really good at dealing with his co-workers who are really hard to [STRIKE]be handled[/STRIKE] handle.

Depending on whether only some, or all, of the co-workers are hard to handle, you might need a comma after "co-workers".

Thank you.
My colleague is really good at dealing with his co-workers, who are really hard to handle.

Depending on whether only some, or all, of the co-workers are hard to handle

what are the differences?

Without a comma, it means he is good at dealing with those co-workers who happen to be hard to handle. It doesn't give any information about how he deals with the rest of his co-workers.
With a comma, it means all his co-workers are hard to handle and he's good at dealing with that.

Thank you.
My colleague is really good at dealing with his co-workers, who are really hard to handle.

what are the differences?

The use of the comma there indicates that all of his coworkers are hard to handle. The omission of the comma would indicate that only some of them are hard to handle. (If you want to use just one word you could say they are difficult.)

Though there's nothing grammatically wrong with using "really" twice in the same short sentence, stylistically it come across as unimaginative. Also, in my opinion, "really" should be avoided in formal writing.

with his co-workers who are really hard to handle.

How about the/those instead of his?
