Can you find an excuse for me?

I'm in the security business of a site. 4 people work during the day, 4 people work at night... We are the rest days of those who are daytime... The thing is, let me give an example, a friend who works during the day gets a job, and one day they change their rest days with another friend...
To get to the point, a friend of ours during the day doesn't change his rest day with anyone, I heard that the patient is working today, if nothing goes wrong, I'm off tomorrow... What excuse should I find if he tells the manager, "replace me with him"? Not to change? There is no such thing for now, but what if?

You are inside your own head too much in your explanation 🤷🏻‍♂️

"no is a complete sentence"

I'm not on good terms with the man, I didn't want to change the rest at the time. The principal doesn't know we're on a spree, so...
