To me this is just arrogance and probably even irresponsible. If I employed someone in my company and if I could fire the person at a moments notice, then I believe the employee and his skills were not leveraged to the benefit of the company in the first place. I agree company's shouldn't create exclusive dependencies with employees but if nothing is affected by letting an employee go suddenly or if the employer didn't have to think twice before doing so, then the employee probably wasn't needed in the first place. Both the company and the employee should be invested in each other in terms of skill, effort, time and compensation. Not to mention that you just burned a bridge that you didn't have to.
