Thanks everyone! You have all been so supportive. I do think dcm asking me last week about the change in hours was my "notice"... She said her hours change June 1 so that is the date I will be going by. I am doing to ask at pickup today what area they are planning on moving to and that will answer my question. I doubt they would continue to drive further East just for ME.
Its her attitude that has been bothering me. Not the fact that they are moving, or the notice period, its the "Oh we didn't tell you..." She knows that she didn't.
