Okay kiddo, so imagine you are part of a really big group of workers, like a school class or a soccer team. Now imagine that someone from that group had a special role where they were in charge of making sure everyone was safe and happy while they were working. That person would be like a leader, but instead of being the boss over everyone else they would be more like a helper.
This special role is called Father of the Chapel. It's a title given to a person who is elected by the workers in a big group, usually in places like factories or offices. The father of the chapel is responsible for making sure everyone is treated fairly, that they get paid on time, and that they have a safe and pleasant work environment.
So, the father of the chapel is kind of like a captain of a ship, who makes sure that everyone is doing okay and that the ship is sailing smoothly. In this case, they make sure that the workers are happy and protected while they are working.
I hope that helps you understand what a father of the chapel is!
