I accepted a contingent offer on a new job last week and am now waiting on background check and drug screen to clear. I wanted to wait until everything was finalized before I give my current job 4-week notice. But now my manager(s) are asking me about holiday shifts and about training new nurses. I am not worried about anything bad being found. I am worried about things being delayed (due to COVID). I already have a start date for the new job.
Would you wait or go ahead and tell them?
