Just because you call the method Post, it doesn't mean that it will accept HTTP POST method. You need to decorate with [HttpPost] attribute.

GET is the default; so you don't have to decorate Get methods - but I consider it to be good style to put [HttpGet] as well.

Note, that you will probably get other errors, regarding submitted data; but at least the system will find a method that will respond to your request...

One more note - it is very unusual to put HTTP methods in model classes - that's what you have controllers for. So you may not even be able decorate Get/Post methods, if they are really in Department/Employee classes

UPDATE: Probably the last paragraph (Get/Post in Model class, rather than in controller) is the root cause of the problem!
