Is there a cut off time when talking to parents when we are off work? Solution: (Rates are posted for this solution!) I believe a personal number is not appropriate, however, a business line or number should do fine. If over the phone is your preference for communication that is fine. As long as you specify what specific times you are available after school for parental concerns it can be an appropriate method of communication.
