If you provide professional advice to the world at large you will encounter bad reviews from time to time.
The single biggest cause of these reviews, however, is not your advice. It is the gap between the expectations of the person you are advising and the reality of the situation.
If someone comes to you with an expectation that they have a legal case or cause of action or an entitlement and expectation that their employer must pay them off with some type of severance package and the reality does not accord with that expectation, then you are at risk of a bad review.
Unfortunately, there is nothing you can do about it. And sometimes no matter what steps you take to explain the situation clearly and professionally you are flogging a dead horse.
The person simply won’t listen and think they are entitled to a deal from the employer and expect you to wave some type of magic legal wand and get it for them.
It doesn’t work like that.
So you can get ready for a bad review, even though it is wholly undeserved and unjustified.
