To be sick of writing a reference for her?

[MiaMarshmallows]

I agreed to be a reference for a colleague last year. Since then I have been asked to write numerous references as they seemingly never get the job they want.
AIBU to say I want to be taken off the list as a reference and also, has this happened to anyone else?

Why do you assume she is getting the jobs then turning them down/quitting, rather than just not getting the jobs?

Another who is confused as to you saying she is getting them and turning them down.

MY dd has had 4 jobs since she finished her degree last Summer. She isn't turning anything down - the jobs 'cease to be' because the leisue sector, the hospitality sector, the fitness sector and the retail sector have all had to shut their premises. So she ends up back to square one - job hunting again.
My dn, when unemployed a couple of years ago, had it happen more than once that a job was advertised as being either doing X or being paid Y or with T&Cs Z, got as far as being offered the job to find the offer came through with nothing like X, Y, or Z, and so, yes, in those circumstances, he turned some of those down.

If you know that she is actually being offered genuine jobs and turning them down, then, that is quite a big thing to omit from your OP, as that would have been an entirely different question.
