Management who speak almost exclusively in abbreviations, acronyms and initials.
This really bugs me as it's supposed to save time but it's pointless as nobody understands it.
We had a team breif followed by refresher health & safety training on various machines at work today. It should have taken about 20 - 30 minutes but because it was spoken in management gibberish it took nearly an hour as they had to explain what a "tpp(slash)sop" was. If they had simply used the words as written xxxx xxxx packing standard operating procedure. That example was one of the more obvious ones but even though I've been there 3 years struggled with the more cryptic stuff.
How they expected the 20 new starters to understand I don't know.
The annoying thing is the training files and team breifs have the correct words written in them, it's just management trying to sound knowledge.
