Due to a recent and unexpected turn of circumstances, I have been offered the chance to begin school much earlier than previously planned. Because of the work needing to be done between the date I begin school and the present time, in addition to other unforeseen circumstances beyond my control, I regret to inform you that I must tender my resignation immediately. I will be unavailable and unable to work any future shifts, as of today.
Since my resignation occurs after the end of a pay period, I would like to collect my final check on Thursday or Friday night, whichever is more convenient for you. If there are any additional vacation hours that I have accrued but have not yet spent at this time, please add them to my last paycheck; if this would put me over an 80-hour workweek, please use them on a separate paycheck which I will pickup at a future date (again, whenever this is convenient for you).
I regret that I am unable to give any further notice or work any additional shifts; thank you for giving me the opportunity to work for the Best Western for as long as I have, and I wish you good luck and success for the future of the hotel.
