Yeah it’s really tough at the start of your career. Low pay, long hours, no vacation, and starvation if you don’t play ball. My advice is don’t allow yourself to feel loyalty for any company or anyone in a higher position than you. They’ll act like they’ll have your back but the moment the calculus says throwing you under the bus is beneficial they won’t hesitate. They won’t give you the raise you deserve, so the only way to get that is to jump ship whenever it’s beneficial for you to.

They don’t owe you anything more than the agreed upon compensation, you don’t owe them anything more than what’s in the job description.
