Your relationship with your employer is inherently antagonistic, and anyone who tells you otherwise is selling you some BS. That doesn't mean you can't work well together, but sometimes your interests align with the company, and sometimes they don't.
You can compare this to big game companies, which have no problem hiring a bunch of people and then laying them off when the project is done. All the disadvantages of being an employee (IP assignment for side projects, low pay) with all the disadvantages of being a contractor (no income stability).
Companies do what they need to in order to survive, but that doesn't mean that the people running the companies are always 100% soul-less
Your employer will not take care of you. It is your job as an employee to make sure they meet you halfway.
