You said, and this was consistent with Mr. Barrière's observation, that during meetings, especially when they were virtual, managers often spoke to people in English. You even said earlier that correspondence was sometimes sent to you in English, that you asked that it be sent in French, but that your request was denied. This is really a violation of the Official Languages Act.
What can you do in cases like this? Do you routinely submit a complaint when it happens?
That said, if employees file a complaint, they should be a little afraid of reprisals.
How do you see this situation? What action could be taken?
