This is the second night in a row I have accepted a job only to have it cancelled immediately after. Last night it happened twice. I know what is happening. Teachers are putting the jobs in and in contact w/ their preferred sub. If the preferred does not pick it up because someone like me gets to it first, they are cancelling it and putting it back into the system My district does not allow subs to be requested and its upsetting that I am doing the work to find a job only to have it cancelled. calling the sub desk to gripe tomorrow.
