Everyone should keep this in mind for every type of contract. In the beginning of my adult life, I was under the expression that contracts were static and immutable. As I got more experience, I tried being more demanding (and my skills were also more in demand) when setting up contracts and I have at multiple points managed to change what was supposed to be "mandatory" and "unchangable" many times, from rental contracts to employment contracts and many other things.
