I work in the President's and Provost's office and I can tell you we get calls from parents ALL THE TIME! Grades, questions, some we can answer and help, others have to be sent somewhere else.
The WORST case of interferring was about a month or so ago when a parent called to complain that their dd did not make her sorority and her roommate did??? She said it wasn't fair. What could we do? AND, if we really did have the "power" to let the girl into the sorority that she didn't make, did the parent actually think she would be welcome? From speaking the to Dean of Campus Life, the two girls were actually good friends and roommates but once the other girl made it in and pledged, the MOTHER, not the child requested they be moved from the room (her dd).
At the beginning of the semester, we also got a call from a mom saying her son had not be cast in the musical and he is wonderful and should be lead (yes, this is for real). The mother asked that we please do not tell the child or the teacher she called but wanted to know how will this help him in the real world if his feelings keep getting hurt??? HELLO, if he is in the theatre program, he is in for LOADS of disappointment for casting calls, auditions, etc in the REAL WORLD! Is his mother going to call the director????
We have parents call and complain about ANYTHING. And, while I can understand having a say when you are paying $42K+, some calls, like above, just SHOULD NOT be made.
OK, sorry, I guess I am venting. Getting ready for commencement and in about a month or so, angry parents will begin calling to find out why the heck their child isn't graduating since they haven't been aware that they are short credits????
So yes, parents, mostly mothers, call ALL THE TIME!
