I've taken on a wide enough variety of projects my manager has joked that "Jack-of-all-trades engineer" would be a good title for me. Yesterday our head of HR called me in to discuss moving from temporary to permanent. She said that they are looking to create a position that would encompass my roles in the organization. She said that they are not ready to offer me a position yet but would send me a letter stating that they intend to make me an offer once an appropriate permanent position becomes available.
After the fact I realized that this letter does not seem to add any value for me. Their intentions are made clear from our conversation and so far as I know the letter would not be binding in any way. Should I go back to HR and let them know that the gesture is unnecessary or let them go to the effort of following through? Is there some possible value to this gesture that I'm not seeing?
