I am currently the technical supervisor of a hospital laboratory. This is the first supervisor position I have held since graduating with my degree 5 years ago. Laboratory technologist is what my career is and has been, I went to college specifically for this type of work. I have been wanting to leave the medical field to pursue an education career, teaching and eventually specializing in learning disabilities. My manager is the type that is aggressive, she is always wanting me to take on more responsibilities and holds me to a very high standard. That I can handle and am ok with. I have really become very indifferent to this industry because I have seen a lot of behind-the-scenes stuff that has changed my perception of the field entirely. I really want to make the transition, but my manager is still pressing for me to take on more. Especially, now when we are incorporting some new instrumentation that requires travel to a training facility. I am her main choice to attend this training. I feel it is unfair for me to do this when I don't plan on being there past the summer. I do have some other issues outside of work that are also helping me make this decision, which she is somewhat aware. I have not broke this news to her, and have been trying to figure out how to tell her of my plans. I have already enrolled in an internet program to pursue the teaching career and only have about 6 months left to complete the program. I need feedback or advice on how to tell my manager of my change in direction, that I won't be here too much longer and that we need to find someone else to replace me. Plus, the issue of the instrument training, finding someone else to go instead of me. Any insight will be appreciated, I just need help on the approach and what to say since she is very aggressive in nature and can be very persuasive. Not one to take "NO" for an answer without a good explanation.
