Well, assuming that they're employed and not on probation, they're doing their jobs appropriately.
Workers in Japanese car factories start their work with the company song and some exercise .... I don't see them complaining right now.
My point being... if the biggest complaint these airline employees have is reciting a paragraph then they're doing ok, in my books.
By the way, I did work for a large american outfit and we (sales / marketing) were fully expected to know the company's mission statement. If we were asked during a company meeting and forgot .. drinks were on that person. The financial loss would have run into US$500+ range. Never heard a single person whinge about it.
