Whether you are a student or already have a job, chances are you will be asked to work together with your colleagues to reach a particular goal. This might be a simpler presentation or a report, or a more complex project over a longer period of time. No matter what your project is, it is essential to be able to carefully make a detailed plan with specific aims and then collaborate with other people to meet those goals
This can be difficult to do in our own language, so it should not be a surprise that working together on a project in another language is even more challenging!
The good news is that using your English in these kinds of situations is excellent practice, and can also help you to develop other kinds of skills that are valuable for practical life situations as well as being successful with job interviews, getting a promotion, or furthering your career goals.
