Tracy,
First let me commend you on your effort. It is a huge undertaking and certainly a valuable resource.
One topic that you may want to consider is "balancing personal and professional life." The stressors involved in raising a family, managing your home, being a wife, volunteering in your community, "soccer mom" and then working shift work in an inherently dangerous environment can be overwhelming especially to new hires. Just a thought.
Good luck with the training and if you get a chance please let us know how your first presentation went. My thoughts are that the class will provide you with a host of other topics and you will be able to build on what you have in place.
