Employment should, in fact, teach children to assume responsibility. It may teach them to budget and spend their money wisely. Too much cash at the hands of vulnerable teens isn't always a good thing. Suggest a banking and spending plan for their earnings. Working too many hours is a valid concern to many parents of employed teens.
Good help is simply hard to find.
Obviously summer vacation allows for a bit more freedom with the absence of school schedules, but don't forget that kids still need to be kids. They will grow up soon enough, and find themselves in a position where work is mandatory and not simply a means to finance frivolities. Workplace accidents are on the rise, and teens make up a surprisingly high percentage of the work force. Parents should always inquire about an establishment's safety record prior to allowing their son or daughter to seek employment there. Obviously accidents can occur anytime and anywhere, but if an employer has a reputation for accidents due to carelessness, it might be best to have your child apply for a job elsewhere.
