I think my supervisor hates our intern. She's always complaining about how he's not performing at an adequate level, and that he's not as good as our previous interns. Which is true, to some extent, but that's because our previous interns all tended to be amazing, so this guy represents a more realistic standard for the kind of intern we can get. Lately she's been saying she's thankful we only need to deal with this intern for two more weeks, when his internship ends, and we can get someone new.
I mean, I work with this guy pretty closely, and I can tell he's a hard worker and quite professional. It's just that his language skills let him down sometimes. But when I try to point this out to my supervisor, she gets even more irrationally critical of the intern. I have no idea what her problem is with him, she's usually not like this.
