There is nothing immoral in self-interest as long as you fulfill agreed amount of work or services you agreed in your contract. Company doesn't care about you, that's the reality you need to be aware. Most companies will respect their obligation they took from their side of the contract, but the moment they don't need you anymore - you're done, fired. Everybody needs to be ready for this scenario. It will happen to everyone, at least once in their life. The best way to protect your self from this is to have some other income on the side. Either investing in your own startup or something else. You owe to your self that much.
