Due to various minor conflicts my manager has asked me to resign. Its a situation in which I'm really not a great fit for the team rather than any specific cause for termination. Because of that he gave me a few months to look for another job. Now I'm coming up with two weeks left on the job and I'm ready to let my team know that I'm leaving. But I haven't lined another job up yet. So I'm unsure how to announce my resignation without indicating that I've been terminated and in a way that will keep coworkers from asking about my next gig (since I don't have one). I want to keep the level of awkward at a bare minimum. In the end, I have already handed in my resignation, so the topic of whether to resign or wait until they fire me is moot.
My question is therefore, what are some great ways to communicate to coworkers that I’m moving on without indicating it was an involuntary termination and that I’ve yet to secure another job?
My goal is to reduce awkwardness as much as possible.
EDIT: I sent the following email to my team yesterday afternoon
Good afternoon Team,
I wanted to let you know first that my last day at [business] will be on the [day]. I sincerely appreciate having had the opportunity to work with you all. I’ve learned so much from each of you. Even so I am looking forward to the new challenges my next position will bring. [My Boss] will be making the announcement to the full department tomorrow. I’ll be sure to send out my final farewell later later on with my contact information and linked-in profile.
When they ask, I'm considering saying something like "Ill let everyone know [where I'm going] in my final farewell letter". Hopefully I'll actually have an an offer by then.
