I work in an unhealthy environment. What should I do to get myself out and still employed?

There are three employees and two supervisors that are making life as a housekeeper difficult. Especially concerning when we're cleaning up after surgeries, yet no hazard pay or special duty pay.

This has been going on for a few months now and I am just at the end of my rope. I want to go to school in Australia or Germany or even in another state.
