I guess for many parents, it can be hard to find a place for your child's work experience.
So it may be a bit uncomfortable to see your manager bringing in their acquaintance to the office for work placement. Presumably the boss does this so that his own children may receive the same favours from someone else.
Sometimes it gets worse when the boss asks you to take care of the person and then disappears. So for about ten days, you have to find something for that person to do, etc.
If you are in this situation, is there anything you can do?
