Supplementing university income - how?

[teentantrums]

I teach part-time at a European university and need to supplement my income but it cannot be more teaching due to contractual issues! I just wondered if anyone has any ideas of what else I could do from home? Thinking of possible exam marking - is that even a thing these days? Or any other ideas? I have an (practically unused!) PhD too.

Bar work
Exam marking
Train in something like counselling that you can do from home

A level exam marking maybe, or tutoring.

Proof reading and translation also used to be good but AI has taken a lot of it.

Do you have quantitative skills - coding / statistics etc?

What's your field? I know some classicists who make extra money during the holidays leading group groups around Greece and Italy. They're paid guides, not organisers, and it seems like such a nice gig!

Do you have an area of expertise that is monetisable in any way? Writing (a trade book on a hot topic - some publishers actively seek this kind of thing), a podcast/youtube channel? Not exactly a route to quick megabucks, but something.

Professional copywriting or thesis copyediting? https://jobs.scribbr.com/ - there are several such companies.

Does it need to be academia-adjacent/career building? In the very short term, as other's have said, cafe/bar work might plug the gap.

Academic translation still has legs, but you do have to know what you're doing.

A friend of mind did indexing of academic books as a side gig. AI is not quite up to the task yet, so this might be a possibility for you.

Consulting -- govts, ngos.

Set yourself up as an educational consultant giving advice on making applications to post-grad programmes eg what is a research proposal, what is a personal statement etc. Something like Crimson Consulting but for post-grads.

What field are you in, OP?

And how much supplement are you looking for? I mean are we talking a couple of thousand a year? Or tens of thousands a year?

Is there opportunity to do some consultancy? If you're in sciences and get yourself on the patent consultancy circuit, there is absolutely tonnes to be made.

Thanks for all the ideas. Quite a few only seem to be open to UK-based staff, though. I am in language teaching and testing and feel pretty underqualified for most of these posts!
