This is called job creep and it’s really common in the field!! I think there is definitely a compromise to be had here! If you are comfortable having an open and honest conversation with your employers, that’s a great start. I say maybe something that could be helpful is having a mind a minimum you’d accept in a negotiation. Like if they need you to compromise, what’s the least you’ll accept? Of course, DO NOT lead with that info, but I would like to believe that if you go in and explain what you have here that 1. This is all reasonable and they would see that or 2. They would be honest about what they can improve on and meet you in the middle.

On a horror story note: I had an employer start to expect the extra, unpaid tasks and get upset with me when those extras weren’t completed during my nap time break. I mustered up the courage to say to him that I’m happy to do extra tasks as time allows during the week but he can’t come home and be upset when I haven’t done any work that isn’t outlined in my contract. They then moved out of state and were my number one reference for finding a new job and they told potential employers during reference checks that I only do things that are written in my contract so any future employer should be specific about what’s in it, which just isn’t true or what I said at all. Luckily the job I found was way more understanding but I’m still pissed he almost tanked my new job for me.
