To be annoyed someone has lifted some of my work and used it in a presentation without at least asking?

@Lex345 So you know the person who passed off your work as their own? were they giving the talk? can you password lock all your work or something so they no longer have free access to it? I would perhaps send a block email stating that your work was stolen and used without your knowledge! if your boss is not going to say anything then go above to the next boss! that is an awful thing to do!

I think you've answered your own question as to how to approach it.

This is good. Make it more about wider context and simplification.

Express concern that it might lose accuracy if added randomly in this way and you'd appreciate the chance to review it.

Once 4 or 5 people have the information, the floodgates are opened and they could each have shared it with multiple other people .... suddenly 4 or 5 becomes 30 or 50 or ....

Another way of looking at this @Lex345 is "who owns knowledge?"

we all stand on the shoulders of giants. The work we produce won't be 100% ours, we have formed our ideas from the concepts, frameworks and theories of others, in my case from the collaborations I've had within our organisation and from my technical background - I'd never be able to thank or acknowledge all those great minds who have influenced my work, there are too many great minds! We've added value, insights and taken it to a new level, and someone else will do likewise 😊

i think they said only 4 or 5 people have access to that drive but I might be mistaken.

This is plagiarism. Call it out. No-one has a right to use your original work without attribution.
Permission would be nice, and the professional thing to do, but failing that, work should be attributed and acknowledged.

And to add, I say this with experience of working on a project currently, that is specialist and technical, and I've seen materials that I've personally created being circulated far and wide and nobody has credited me directly. I take the view that if people are using the information, that's a professional complement, they wouldn't use it if it lacked voracity and credibility, so I must be doing it right!

The OP said it was on a shared drive…

I would start the conversation directly with the person concerned, behind the scenes and in a non-judgemental, non-accusatory way. Assume positive intent, or at least that the person you think has done you wrong, may not be the right person to aim your frustration at. The last thing you want to do is go all guns ablazing (figuratively speaking) accusing them of stealing your work if it wasn't their intention and / or if they got hold of the information through someone else without knowing it was yours.

ask them where they got the information from, before telling them they're unprofessional. In an academic setting, it is custom and practice to credit all work to the author, but information in organisations flows round a lot more freely and the originator isn't always credited. Not good, but it happens.

Just email the presenter and explain that you noticed that they have used your work in the presentation and you’re not sure have they came to be in possession of it, but it is part of a larger piece of work and you are concerned that without the context it is not representative of what the work was about.

Also email the people who have legitimate access and explain that you were at a training session where your work work shown as reiterate that it is not for sharing without prior discussion because without context it can be misrepresented

I am not sure how to "enforce my ip"

You don't own the IP for anything produced in/for work. Work does.

This. Once you prepare something in the workplace, it belongs to the organisation. In my place of work, it would be fair game to use it for the good of the org for whatever purpose and in any future materials. You don't own what you create in work, work does. The best mentality would be "this is being used for the good of the company", and that's the right thing.

I'd have said something in the training, "oh actually that's been taken from something I'm working on, there's going to be more training covering that in more detail but in the meantime do you want me to give a bit more context and talk it through?"

But if I produce things at work then I fully expect other people to use it. Clearly they're the ones with egg on their face if they haven't properly understood it. The fact that it's not been trained out properly is the issue, because the person who put it together didn't understand it and the "trainer" wasn't trained.

This happened to me many years ago before we were all so tech savvy.

I went to a course where someone presented my presentation badly and without understanding the content.
at the break I asked them about the origins and they blatantly lied.
so in the afternoon session I starting asking questions about the basis of the work, how they formulated x and y. It was clear to all they hadn’t done it.

I then emailed my boss and theirs explaining where I had delivered this, that their delivery was poor and actually not correct in legislation. That I was happy to provide training to them if they wished to continue to use it. That I expected an email to go out with acknowledgments and a corrected version of information or I could disseminate this information myself?

got a very sheepish manager on the phone with no idea this wasn’t their work!!!

Yep hide it

Mice-tasty. Or so so my house foxen says

Absolutely make it not shareable at least until you have presented it.

I'd take it as a compliment that it's obviously a good piece of work if they chose to use (steal) it! But yes, I would be miffed I wasn't acknowledged.

Well this is re enforce your IP
But it does not seem appropriate since the company owns your work
Enforcing Your IP: Tactics for Protecting Your Assets (lawdit.co.uk)
However. If you intend to you the unbowdlerised version of your work, you may say This was used previously in an unauthorised version of my research.
God, I learnt that word unbowdlerised from my dad. Legend

random question do you like mice ? @Lex345

I wouldn't go to the person who plagiarised it

I'd go their bosses boss
