Yes, I think speaking other languages is really helpful at work. For example, if you work in a company that deals with clients from other countries, you can talk to them directly. It also makes you look good to your boss because it shows you are willing to learn. Plus, if you travel for work, it's much easier if you know the local language. It can also help avoid mistakes when talking to people from different backgrounds.

Not really, in some jobs you don’t need to speak another language at all. For example, if you work in a small local business, everyone probably speaks the same language, so it’s not necessary. Also, nowadays you can use translation apps if you really need to talk to someone who doesn’t speak your language.
