I hope to make the career transition from the veterinary field to medical records field in the next few months. I attend school at night for coding. I have a wonderful boss and feel I should let him know of my intentions of leaving his practice so he has time to search for my replacement (I am a supervisor of vet technicians). I know some managers give notice of up to six weeks, but I will probably transition into an entry level health record position and don't know if they would be willing to wait that long for me. I don't have anything lined up yet, but am looking. Do I let my current boss know that in the next few months I plan on searching other employment? I have asked a college career counselor and she advised not to do this. We have a good relationship and I have a lot of respect for him and want him to be able to find a good supervisor to replace me. I know it was difficult for him to fill the position when he hired me.
