Thanks for posting -- interesting article. I have not heard any reports like this from the businesses I have as clients. My son reports having been contacted by one of his teen-age worker's parents concerning a work schedule that the teen had specifically requested.
On a personal note, I do remember sending lots of leads to my son from Monster, etc., when he was finishing college. The school's placement office was a great asset to him getting that first job. Still there after nearly 2 years and has had one promotion...
That sounds a lot more reasonable to me than these so-called "adult" applicants bringing mommy or daddy along for an interview. Parents do (and should) have some say in the actions of their teenagers. IMHO, the lack of communication on the schedule, though, needs to be sorted out by the teen and his parents, not by his employer.
