[anyone could have cut my lock and added the booze them a new lock which i was not present ]

If you can seriously
make that argument and prove it you would prevail.

Searches are legal unless the
employer has designated the space as your own private space and you have an expectation of privacy.

It may be that you do here and that they violated applicable local law.

Have a quick chat with whatever labor board governs your work.

can you elaborate more on the privacy laws ?? .. this may be what i'm looking for ..
