The person I work with is trying to shift their responsibilities onto me at every opportunity. Sometimes it feels like they’re helping without realizing it, but then I realize that I’m literally taking on everything. If I speak openly, it will damage our relationship, but if I don’t say anything, I just get frustrated. What do you think should be done in such a situation? How can I solve this without disrupting the work environment?
I’ve experienced a similar situation myself. At first, you think, ‘I’ll help out,’ but then I realized that my work is never done, and their tasks are shifting to me. I spoke openly and said, ‘Let’s divide the work; this isn’t part of my job description.’ It cooled our relationship, but things got better; it’s a matter of preference.
But wait a minute, maybe you just can’t say no directly? Sometimes, in places where we think we’re making our boundaries clear, we’re actually making things easier for the other person. If that person can use you so easily, I suggest you take a look at your own attitude as well.
operational fair balance is already a problem in every workplace. The first thing that needs to be done here is to say, ‘this doesn’t fit my job description, it’s not my responsibility.’ But keep it related to the job without dragging in personal issues. Direct communication always brings a longer-term solution 
Let me update you. Actually, this person usually delegates work and makes it seem like “I’ve got this” to management. I considered talking about it before, but on the one hand, I don’t want to jeopardize my own position at the workplace.
I think there’s also a bit of compromising yourself there. People will go as far as you allow them. If it looks like you’re handling it all alone, you can’t solve this without sharing it with your manager. But when you talk, be careful to appear ‘solution-oriented’ rather than ‘complaining.’
Here, boundaries and records seem to matter more than feelings. It would be safer to keep everything — messages, payments, conversations — and then take action calmly.
