First off, forgive me if this is the wrong sub for asking this advice.
I just got promoted but I want to leave the company. The promotion isn’t effective until March 1st. I’d like to resign and have my last day be March 1st.
If my last day is the same day the promotion is effective, can I legally claim the new title from the promotion on my resume? Or will that fail a background check at some future job if someone calls the company?
