This is a question that was raised on a course I am doing.
There are many teachers of English who like me teach for the TOEIC exam. In some companies people need to get a high score to rise in the ranks and become mangers. So I understand that speaking English is a necessity to be in the upper hierarchy of a company. I haven't ever seen a native English speaker with excellent French language skills in a high position in a French business.
Please don't think I am saying there should be or shouldn't be. It is just a question of are there any.
Have you seen or heard of any?
