I'm a third year graduate student pursuing a PhD in Europe. My field of work is computational chemistry (mostly involving developing software packages). In addition to that I have a masters in Physics. My professor instructs courses like computational physics and statistical mechanics.
Moreover, these courses are conventional taught in their native European language (I have acquired A1 certification for the same), but the fact that TAs should know the language is not enforced (I have friends who are non-speakers TAing much more interactive courses). Even after repeated requests for 2 semesters, I was let down by one excuse after another.
First time it was the fact that I didn't know the language (which I have subsequently learnt (acquired A1) and proved to him the fact that it's not enforced). Second time, there was no excuse what so ever, a simple "your time would be better spend in other side projects". And the irony is that I need to know the native language to teach python programming which a computer programming language written in english.
How to approach this?
