So if you decide to set up a business in a country where the first language is not one you speak, it might be an idea to learn it, no?
The first language of this country, the UK , is English. But that really isnt the point. Its a management matter in the case quoted and something management are perfectly entitled to insist on in their workplace.
For example, in an Italian restaurant in the UK they might well insist on speaking Italian only in the kitchen as a practical matter.
What about "because it's their first language" or "because it's how they communicate at other times" or "because it's a Welsh-speaking area"? Mind you, the boss doesn't exactly sound worthy of any respect.
If you can speak a language and choose not to despite one of your number then not being able to join in / understand you, then at best it's bl**dy bad manners and at worst its deliberately being difficult. I suppose its up to you if you decide to do so socially, but its a company policy issue if you try to do it at work.
