A working interview is a good option to get a better idea of how someone fits into your team. You may also want to setup a more formalized training. Many people leave a veterinary facility because they get stressed over not feeling like they have really been taught how to live up to the expectations of their employers. This is especially true in a situation where the work day can be so extremely varied as in the veterinary medical profession. And the lack of recognition/appreciation is also a cause for high turnover in veterinary facilities. So rather than just the typical on-the-job training, getting new hires involved in either going to school to be a veterinary technician or at the very least earning a certificate as a veterinary assistant so they get more balanced training and can get recognition for their accomplishments can build a better foundation for good medical care and build a personal feeling of accomplishment.
