YuP sometimes some income is better then no income : )
When I first started I had a client with rotating shifts 1-4 days a week and every week was different so took up a full time spot .... We made a deal that they paid my part time rate for only the days they were here plus all stat days regardless if it was a regularly scheduled day as well as my full vacation days .....I was glad for the money at the time but when they had to take her out due to mom going on sick leave I was not disappointed . So I hear ya but I would still try to get the parents to drop off a little earlier
