But I guess the "kids" think it's funny to use text-slang instead, further exposing their ignorance and lack of respect for others.
I realize you're being rather tongue-in-cheek - but I wanted to say...
I work at a university, routinely interact with student workers, and have to say - these sorts of "stories" are garbage. Kids vary in terms of their work ethic, as has always been the case. There's nothing particularly different about recent generations compared to earlier ones. Even the kids who need to improve their work ethic mostly know the right way to communicate with their bosses and co-workers. They get a bit loose when talking to coworkers who fall in their own age group - but that was true even way back when *I* was the new kid.
And, incidentally, back when I was a new worker - trimming the wicks on the gas lamps - there were magazine articles saying basically the same sorts of things to people my age.
The real lesson here (if there is one) is that the folks who are attempting to make a living giving career advice to young people haven't changed significantly in many decades.
