I'm 41, so a millennial, and I know this guy isn't talking about my generation specifically. But it still irks me. We had dinner guests (wife's family we have not seen much) and this guy and myself both own our own business with employees. We were talking about this, and he said out loud, "ya those millennials don't work man! They never show up!" and I'm like, bro. You aren't talking about millennials.

Anyway - that aside, my early experiences with the 25 year old recent workforce entrants has not been impressive. But this is also the first time I'm seeing that new age group come along where I'm the boss, so my views may be skewed.

I regularly deal with young workforce entrants and as far as I can tell there is no pattern.  Some people are unmotivated and put more effort into looking busy than actually being busy, some people have endless drive and will bust a gut to get things done and go home at the end of the day.  The only way I'd say that age is a factor is in my experience it's easier to encourage an unmotivated young person, but ymmv.
