At my company we have half annual discussions between supervisor and employees for development and knowledge stuff.
End of last year I had a very emotional discussion for over half an hour as somebody with a year of experience on why my stuff can be considered under knowledge. He never yielded in the slightest and tried to push me down in every way.

The outcome also reflects on the payment and therefore I tried to argue that we would need a third party, like HR, to help, which was debated down as to me not being able to communicate.

This is just one of the bad things I have/had to deal with.

Sadly I am still at the company mostly for legal reasons...

Still don't know if it was the right thing to debate and not getting in touch with HR :/
