Answer 1

It's about initialization. Try doing this:
Toggle toggle; // create field
...
void Start() {
toggle = workingDay1.GetComponent();
}
void Update() {
toggle.IsOn = _workingDay1;
}

Answer 2

try to translate the error, it will become clearer immediately
1 - Object was destroyed, but you are trying to access it
2 - Toggle type or space was not found (the reference to it must be specified most likely)
