New teacher they want to fire for budget shortfalls. Should I sign the paperwork?

Hello,
I am a first year teacher in Florida. I just found out that the school district is having budgeting problems and my school is going to be “pink slipping” (a.k.a letting go) of all new teachers. When they do this they give you the paperwork and have you sign several documents agreeing to the conditions but they tell you in person that they will be rehiring you when the funds become available (so in their words it’s all a technicality because they say the funds always become available). I have not yet found out if I am being pink slipped but I heard the rumor today and just got an email from the principal requesting a meeting at the end of next week. I assume the worst and am concerned that if I sign this paperwork that it will go down on my record and look poorly if I attempt to get another job should the funds not become available for my rehire. Should I refuse to sign the paper work and are there any other options I should know about?

Thanks,

A concerned teacher
