This is a role-play scenario to work on with your teacher.
You will play someone who works in a small startup company. Your teacher will play your manager.
One of the key skills in business is being able to say something negative without upsetting people.
Your boss has had an idea for a new way of working. You think some of it makes sense, but some parts of it are really stupid and will actually make things worse.
Talk to your manager and explain your thoughts, but try not to make him feel angry or insulted.
