Never believe that bullshit. Take what you know you have. I would have politely asked for the promotion on the spot, and a written contract to back it. Otherwise, I have to leave. It's not personal, it's business. Economics is cut and dry - you have to sell your labor to the highest bidder!

Ouch

Check to see if you can still get the other job, and if not, then tell your boss you'll see her in court. She legally cannot do something like that.

Looks like u da dummy

An oral agreement is only as good as the paper it's written on.

The lesson? A bird in the hand is worth two in the bush.

Was the promotion going to make that job as good as the offered one? Maybe you can contact the other company and still get that other job if it hasn't been filled yet...

I'm not sure whether to click Y.D.I. or not for this. Because you should have found out what the promotion was before you declined the other job. But you should take your boss to court.

Your boss gave you a verbal contract that your boss has to follow through with. Go see a lawyer and get your new promotion.

Verbal agreements can be binding but you need witnesses or somehow get them to admit to it. FYL for having a cut thoart boss.
