Why does working for free have to be the norm in academia?
I’m doing a PhD in Psychology in the UK. Throughout my PhD, I have realised that so many things in academia seem to be treated as if they should be done for free, such as peer review, organising conferences (even big international ones), sitting on thesis committees, and other service work. And these are often expected on top of research, teaching, and admin, which can result in a lot of unpaid overtime hours.
When I asked my supervisor whether this was just the norm, they said yes, at least in the UK, and suggested it reflects a sense of responsibility to contribute to the academic community. I said I don’t think it should be the norm, and that it feels completely unreasonable. My supervisor then told me that if I didn’t like this, perhaps I shouldn’t be in academia at all, and mentioned that the same view had been expressed by one of their previous students, who apparently "just wanted to do the bare minimum for what they were paid for."
Now don't get me wrong. I love doing research and contributing to the advancement of human knowledge, and I am more than willing to work long hours because it gives me joy. However, I don't think it is fair that we have to work for free on certain important tasks. At the end of the day, we still need to make a living, to pay our mortgage and expenses, to take care of ourselves and our families, and to be free enough from financial constraints to focus on doing research.
It is already bad that researchers publish articles (free or pay-to-publish) in journals that then charge universities extortionate subscription fees. And now we are also expected to provide free labour for journals through peer review and for institutions through service roles. That feels exploitative to me. In many other fields, people are paid and rewarded for the work they produce (like book publishing, entertainment, etc.), and I don’t understand why academia should be exempt from that expectation.
It just feels wrong to me. I'd like to hear your opinions, especially from professors who have been in the system for a while. Is this simply how academia works, or should the system be challenged? I'm open to listening to all sides of the table. I haven't been in the system for long so I have limited knowledge, based on limited experience and exchanges with supervisor. So please feel free to correct me as well. I know it's a very controversial and sensitive topic, so please be respectful of each other's opinions :)
