Somehow I misread that part about him speaking English out of courtesy when necessary. Thanks for clarifying.
So in multilingual jurisdictions there can be strong employment protections around speaking one's choice of national language. In this case the article says there was the Welsh Language Act of 1993, which presumably says that citizens of Wales are free to conduct all of their business in English or Welsh and shall not be discriminated against in any professional or government capacity for speaking either language as they please.
It's about workplace expectations that derive from the local culture. The hypothetical comparison that comes to mind would be if California adopted Spanish as a second language or something.
