Understanding GenY demands in the workplace

A little unclear as to what GenY is – so I checked the source of all knowledge (ahem), Wikipedia, and it says no precise date, but anything from mid-1970s to 2000s as a start date! I think I fit most of this, so mid-70s works for me… but it appears that it’s making the same ‘digital native’ mistake as many others have (something I am still cogitating on – yes – there’s a cultural factor there, but it’s more about a mindset).
