I was offered a job on the spot recently without actually looking for another job, and after discussing with my now new employer about my credentials and what I could provide them they offered me nearly double the yearly income as what I was previously getting paid. So of course I took the offer. Put in my 2 weeks trying to be professional. Old boss asked where I was going and I made the mistake of telling him. So what's he do, calls to complain about them poaching me from his company. I live in an at will state, and never signed a non-compete contract. And even if I did it's a company in a totally different field of work. So rather than try to match my offer to keep me, he tried to ruin my chances of moving on to something better by calling and complaining that they are putting his company in a bad position with my leaving.
