What can I do if I was put on unpaid administrative leave as a teacher?

The principal walked in during first period and said I need your keys and computer. You can meet me downstairs. When I did meet with the principal and assistant principal, they said I was being put on unpaid administrative leave. They stated that they could not give me a reason. They stated that someone from central office would be contacting me, and it is now 3 days later and no one has contacted me. There is nothing I can think of that would warrant this type of outcome. What are your suggestions?
