One of the companies I worked at decided at some point that they had to hire "millennials". Not for their depth of knowledge, experience, maturity, or commitment, but because they were "millennials".
The dress code was updated and we had an all-staff meeting to impress upon us the incredible wisdom of this new strategy and how we better embrace it wholeheartedly. Oh, and how much we were going to learn from them!
Soon after, the half-shaved heads, earrings, tat sleeves, and beards started popping up left and right. Not too early, mind you, because millennials apparently work on their own time. So we moved the early meetings to times that would be more suitable to these "bright young individuals".
We worked diligently to train them and bring them up to speed on basic IT-concepts like redundancy, resiliency, coding efficiency, multi-tier concepts, and latency.
Long-term business strategies were abandoned in favor of "hip", "modern", and "nimble". We were a content-driven media company, but it was decided that "people don't read anymore" and the articles were cut down to just a few paragraphs that contained little to no substance.
Not long after that we became familiar with the concept of "ghosting" when the new blood decided that 'tenure' of a year or more was "tying them down too much". They simply accepted a new job somewhere else but never told their manager, or simply sent a text message. Apparently the intensity of formally resigning was more than their delicate free spirits can handle.
To date, the company still hasn't figured out what went wrong.
Curiously, my current (Fortune 500) employer has banned "panel interviews" because it's just "too confrontational" for millennials and snowflakes. Never mind that they're likely to have to participate in high-sev incident calls with hundreds of people on the call - including executives.
Correct me if I'm wrong, but it seems that this is the first time in human history that mature, skilled, experienced staff have been compelled to sit at the feet of the youngsters "to learn from them" how to best to our jobs.
