No matter what you say to your current employer, NOTHING is going to change.
Do not wipe out a four year job reference because you want to pointlessly even the score for a couple minutes.
Your next employer only wants to know four things - dates of employment, job description, salary or wage history, and, are you eligible for re-hire?
Screw up one of those things, and your resume for a new job goes straight to the shredder.
Welcome back to the real world. It only hurts for a couple of minutes.
Your next employer only wants to know four things - dates of employment, job description, salary or wage history, and, are you eligible for re-hire?
I was a supervisor for a Fortune 500 company for over 30 years and will tell you categorically that what you write here is not what I would give any employer asking me for references for a potential hire.
All I was permitted to give to anyone seeking references for a potential hire was the dates of hire and separation.
I was not permitted to give any opinion as to whether the person was a good, bad or indifferent employee. No wage history, reason for separation or potential for re-hire were to be given.
Our litigious culture has made anything other than the simple facts of employment history dangerous.
But I will agree that it is foolish to burn bridges with an employer. You may want to return there some day.
