I think you did a really nice thing, AAAAA. You don't even like this co-worker that much and you helped him find a better job. That is kind and selfless.

It's a free market economy out there and your boss should expect that if a worker finds a job that has benefits and a better salary, that the worker will leave. That's the way it works. Your boss is naive. Maybe if your boss gave better benefits and wages, his/her workers would stay around. My guess is the owner of the company will not be so naive and this will not be a big issue with him/her.

Sorry you have an evil co-worker who ratted on you to the boss. Honestly, AAAAA, the place you work sounds filled with awful people! Do you think you could get a job at the manufacturing company too?
