<human>: I am currently juggling between three jobs.  In reality, I'm trained as a teacher, but haven't been able to find a full-time job in this small town yet.  No worries, that'll come one day, and I'm happy with how things are going right now!

At one of my jobs, I teach English which I love.  One of the secretaries is in charge of receiving calls from clients, organizing groups, etc.

Last semester, I had a bit of a nightmare because she paired advanced learners with beginners.  We ended up sorting that out and after that, she asked me to conduct assessments with prospective clients.  She told me to write the minutes on my timesheet.  So I spent some extra time figuring out an assessment system and doing these 10 minute phone calls.  I had to figure out an assessment system on my own time.  Fine, whatever.  

I don't think her boss knows I'm doing the assessments for her, because when I mentioned it in front of the boss, she gave me a 'wink' and I shut up right away.  The whole situation struck me as odd.

Now she is e-mailing me and asking me to call previous clients and ask them if they'd like to renew for more group sessions.  She said she has previously called them but they have not called back.  In her e-mail, she made it seem like it's a favour I'd do for free, but is it fair to do these things if I'm not going to get paid?  I'm not sure how to respond to her.  She's a lovely person otherwise.

Can you summarize the given text in a few sentences?
<bot>: Secretary at job asking me to reach out to clients when  it's not my job to.  Now she's asking me to phone clients as a favour and I'm not even sure I'll get paid.
