I recently was forced to retire due to illness. While sick, the school district I worked for the past 26 years, threw away all my personal belonging.

Used personal items are unlikely to have a material financial value, and thus the value of the legally recognized damages you have suffered may be insufficient to warrant pursuit of a lawsuit on an economic basis. Moreover, the government subdivision that operates the school system may be immune from certain kinds of legal actions. Have you considered making a claim under your homeowners' insurance policy? Alternatively, have you considered a small claims suit?
