What should I do when asked to resign or be dismisses as a continuing contract teacher when I feel that due process has not been given?

I am a PE teacher at a High School. I was called into the office to meet with the principal and the county clerk. I thought it was just going to be him and had no idea why I was brought in. At that time they deemed the incident severe enough to put me on administrative leave with pay and was to hear from them later about what the next step would be. I was called thursday morning and asked to meet with them at the school board office at 1:45 in which I did. There were 4 of them which includes the superintendent. I was told that I have until Tuesday noon to resign or be dismissed. I have nothing in writing saying this and need advice on where to go from here.
