<prompt> Human: Firstly, Im relatively new to reddit and have been looking for the proper subreddit to ask this question. This seemed most relevant while looking through the employment flair archives. Apologies if this is off the mark.Heres my story. I accepted a job about three months ago which seemed like and was made to sound like by the interviewers a great opportunity for me. After about a month into the job, I realized that there was a LOT of smoke blown in the interviews and this job is NOT what was expected or portrayed to be, so I started job searching.After looking for a few days, the literal dream job was posted. I applied, did a first round of interviews, and am on my way to my second set. Providing that this job is offered to me, I will likely accept it. Here is my problem. In my current role, I am a pivotal part in an upcoming project, scheduled to go live in 1-2 months which will likely be postponed due to vendor inadequacies, and even further postponed if I am not present. Is it considered a professional courtesy to let my current employer know that I am considering leaving? Ive always been told its the golden rule to never tell your employers you are quitting. But, at this stage in the game, having only been here for 3 months and leaving in the middle of a million dollar product launch, I feel like I owe it to them to give a heads up so they are not blind-sided with a two week notice.Any adviceopinions would be appreciated.  <response>: Is it considered a professional courtesy to let my current employer know that I am considering leaving?No.having only been here for 3 months and leaving in the middle of a million dollar product launchYou have only been there 3 months. You can, and and most likely will, be replaced if you let them know you are looking for new employment already.
