I am a freelance tutor and have been offered a better position for one of the days I work (more £, from home, better company to work for in all honesty) however there are a few complications to the situation that brought me to do the position I am doing in the first place.
For this reason it isn't as unreasonable as it may sound, for me to be asked to try to find a replacement for myself to teach the students.
Trouble is I've no idea how to do this at all without having to pay to advertise it? Other than perhaps asking on social media if anyone knows anyone.
