Dear Giulia, dialogue requires two people. You could say anything you didn't like. If we talk about communication, this is definitely an example of a lack of communication on your part. No one is forcing anyone to volunteer, so we really don't think you have anywhere to go. I'm sorry that you didn't express your opinion right away and that you didn't leave right away if you didn't like it. As for the obligation, you have received an explanation for your tasks, when we see that you do not perform them, the only thing left for us is to oblige, because otherwise we do not need you as a volunteer. Volunteering is an exchange of goods. Everything was explained to you before you even arrived - how much you do, what you do, etc. Therefore, we offer accommodation with the obligation to fulfill certain tasks. If the tasks are not fulfilled, we are here to remind them to do so. If they are still not fulfilled - our cooperation ends. We apologize if you felt disrespected because that is the least we want. But that's exactly how we feel - disrespected considering that you're only now telling us all this.
