My workplace was already competitive and at times toxic - but AI has given my eager-to-progress colleagues another weapon to wield!
The bit that bothers me is the failure to attribute their newly found skills and ideas to the correct source. I recently prepared a report and a colleague (who wasn't even involved in the planned review but cc'd into the email to managers for information) took it upon themselves to put that report through AI and return it to everyone with 'her' comments pasted directly from ChatGPT - presented as her own suggestions.
I know the comments were AI-generated because, on noticing the comments looked so wildly different to her usual writing and thinking style, I uploaded the report myself, and ChatGPT provided almost identical feedback - literally word for word, along with a flawed argument based on misunderstanding of the text. So it was a bit of an own goal in the end for my colleague, but the deception still bothers me.
YABU: All (and even AI) is fair in the workplace these days
YANBU: This is unprofessional behaviour
