I hear ya amotherfirst ... I saw this all the time when I worked in centre care and the centre was open 12 hours a day and many children were left there from open to close

One of the reasons why I have a 'fees are based on 9 hours of care' ... if they truly NEED more than that than they have to 'contract' it ahead of time and they have to pay an additional overtime fee that reflective of 'overtime' they are asking me to work ... I have found that when it is going to cost EXTRA to leave their child while they run errands or go to the gym after work suddenly they are able to manage taking them along with them and staying within the 9 hours
