Background
This is my first serious job and I know too little of the language in this country. I have spent about 6 months with this company, weirdly enough I communicate with most people using a translator.
I always get tasks from the boss in a small team of developers but he rarely asks about the status of my work, but rather asks others about what I did and didn't (what I have discovered lately).
The incident
we had a normal meeting, they said something I didn't understand but suddenly the boss turned to me and asked me whether I have started doing what he asked a day ago or not, I said yes and demonstrated quickly what I did, he turned to the other guy and this time I could understand that he said "he did it why did you tell me he didn't" which shocked me but I pretended I didn't get that either. Then the coworker asked me privately later why I didn't push what I did, I explained that it was unfinished and ....
Question
is it normal in a company for a boss to supervise employees through a co-worker?
