I want to start by saying not all millennials are lazy self-absorbed assholes. It's not responsible to describe a huge population of individuals that way because I do know some that are very focused and driven ~ are achievers. I'm only going to complain about two that I work with.
Both of these young women started out as dental assistants, which is a physically demanding job...then you have to work with the dentist, who can be challenging (and sometimes rather mean, although neither of the dentists I work for would be described that way ~ they are both wonderful guys that are incredibly tolerant). One of them is now working on the business side of the desk, the other is still assisting.
Not long ago we had to hire a new assistant, and she's doing very well. But I heard through the grapevine that assist. #1 won't train her on anything....."because it's not my job". First of all, I really hate that phrase. Secondly, that leaves assist. #2 in a pretty poor spot that is way more stressful than it needs to be. #1 should be showing her the ropes, making sure she understands what the doc wants when preparing for a patient. "It's not my job" is a euphemism for "LAZY", in my opinion.
The other woman now works up at the front desk with me. I like her well enough. However, I think that when a patient comes into the office (you can hear the ding! of the door when someone opens it) she should actually look up and greet them instead of looking at her phone because she knows I will do it. Same goes for answering the phone. It's quite maddening. And here I thought I was "leading by example" but apparently millennials feel that they know everything and can't be bothered to compare their performance to anyone else's.
I hate to toot my own horn, but I try to always be busy. If there's not much going on, I find something to do. I wish that I could say that of my coworker. I really really do. Of course, I sometimes look at my phone too, but it's only for a moment or two, not for 20 minutes.
Are we underpaid? Yes. Most offices pay on average more than we are making, which I know because I've worked in other offices. But if that's your main beef, I think it's time to go look for a new job instead of making everyone else have to pick up your slack.
