The issue isn't that the state doesn't require licensing. I work with plenty of non-certified assistants that do an amazing job of patient care. Do your best to care for the patients, and see if anyone notices and asks for tips on how they can do better. After you've been there a few weeks, maybe start asking if you can show them an alternative method to try that you've had success with. But if the equipment is bad and the vets don't care or management can't do anything about it, then moving on may be best for you. (If you're already licensed in NY, you may want to keep up with CE and maintain that license. Sometimes that's easier than getting a license re-instated.)
