What to say when quitting a job you just started?

In my personal opinion, if you see that the job just isn't the right fit for you, it's okay to say so. As for me, I think this is being fair to yourself as well as your employer. If you notice things quickly, that just aren't working out so well, I think it's good to go to your supervisor and tell them as such. If it were me, I might say something along the the lines of, I really appreciate your time, I'm thankful that you gave me a chance. While I might like everyone personally around here, I'm just feeling this isn't the right fit for me, right now. I hope you can understand.

Be honest. What made you want to quit? Did you not like the job? Did you find something better? Say it. Honesty is the best policy here. But if you're uncomfortable saying that real reason, make something up that makes sense and go with that.

First, I would thank them for hiring me over other candidates and then I would introduce the reason why I am quitting. Remember, you want to end on a good note!

I am afraid this job is not what I have envisioned after all. I feel terrible for having to leave, but I am willing to do whatever I can to make the transition as painless.

You be open and honest and you thank the employer for the opportunity but you've realised that the role doesn't suit your needs or expectations.

That you have given the job and try and its just not the right fit for you, however you are thankful for the opportunity.

I'm really thankful for this opportunity. However, after starting to work here, I've realized this is not a good fit. I don't feel I can do my best work, and this job just isn't suited for me.

As you know I have been at this job for only a short time but I have now realized that this isn't the job for me. Sometimes you do not realize if a job is for you or not until you have actually started the job as I have. There were some things I enjoyed about the job but the things that I didn't enjoy have over powered the things that I did. I appreciate you giving me the chance at this job and offering it to me but i'm sorry to have to advise that I will now be leaving.

Just be honest. It is the best path. If you don’t think the job is a good fit for you just tell them. As a manager, I’d rather someone come to me and tell me they are quitting and be honest to be about why instead of just ghosting the business. At least that way they know if it’s something they should do differently, also then they’ll know you’re fine. Just a little tip, always turn in a notice if you think there’s a slight chance you might work there again. If you don’t most businesses will mark you as not able to be rehired.

I think being honest should and does work. Go to your line manager or atleast the person who recommended you for this post and let them know your intentions . You want to leave this job with the best of relations and there is nothing better than honesty.
