In Fluent Forever's Awesome Word List, マネージャー is used to describe a manager in a bank or similar organisation.
However, doing a search with the basic version of google image search mainly got middle-aged women wearing sporting gear. jisho.org gave me a couple of meanings, a manager of a business, an idol, etc, or someone who does boring work for a sports team. The Wikipedia article マネージャー mainly emphasised meanings outside of a manager at a large organisation. For example, some of the meanings corresponded to an individual who managed a single person in entertainment or sport.
However, the word hasn't been mentioned by anyone in a forum thread about the Awesome Word List and suspected errors.
Is マネージャー a suitable word to describe a manager in a large business?
