You learn French, they learn English, you meet in the middle. I think that’s probably how that was meant to work. Sounds fair to me.
You seem to lack the ability to change perspective here: You learn a language and so do they. You just seem to be missing the fact that the other side is doing the exact same thing?
I never knew there was this much drama about the French language in Canada. Really interesting fact on its own.
Trust your manager and the people who hired you. They picked your for a reason. Sometimes it’s not what you think makes a good employee in this position, but something much more specific to the team or situation you’re in. If in doubt: Ask!
Many times people who come straight from uni don’t feel productive enough, because they can’t be productive for 8 hours straight. But that’s normal. Staring at the ceiling blankly on occasion is normal too. If you’re doing your best and the matter you’re working with is working well for you, then you’re very likely fine.
There’s always a bit of impostor syndrome in all of us, but still try to get comfortable and trust your colleagues. Ask for feedback from your superior, if you’re unsure.
