Agreed! They might even back off if they actually see what they could be doing to themselves. Try it and see what happens. You know what’s coming up anyway. Give it a shot and please let us know how they respond.
I would first try talking this out with my employer. I would keep a list of my concerns handy (agenda items, if you will). If things got more formal I would then move to putting things in writing. Cross one bridge at a time.
Come what may, I would think maintaining honesty and integrity with one’s employer (and in general) is better in the long run than an adversarial relationship.
Since there are no guarantees either way, at least there would be self and mutual respect at the end of the day.
