Unfortunately, there is a large group of work newbies in my library who may never have been told about behavior and dressing appropriately, but they DO know now and still prefer to do whatever the heck they think is most fun for them.
The young ladies complain about men leering at them for example. Now, I agree that men, young or old, should NOT be ogling, flirting with or harassing young female workers. However, as a young female worker once upon a time, I knew that if I quit wearing the low cut midriff tops and the tight jeans, the comments stopped. The woman who is the direct supervisor to these girls (and I am sorry, they are girls, despite being in their mid to late twenties) has told them repeatedly that the security guard will deal with the problem gentlemen, but for heaven's sake, put some clothes on! They insist on wearing clothing that looks as if it has been applied intravenously and only partially and then wonder why men ogle them. Please!
Then there is their work ethic--non-existent. These kids have schedules they are supposed to follow, being on the desk, helping patrons, and so on. Instead, they will disappear from the desk they are supposed to be working at and reappear in the lunch room with their buddies for giggles and candy and pizza. I know this because I will be in the lunch room, overhear their conversation where they brag about how they have left "old fogie coworker" sitting alone surrounded by patrons, and giggle about how cool it is to have a pizza party.
They have been written up, talked to, warned, written up again--and they keep doing it because the people who are in charge of them don't want to have to fire them. Apparently having warm bodies somewhere in the building (even if they aren't doing their work) is better than not having any bodies at all.
I'm not sure this is a generational thing either, but I'm seeing it a LOT from the youth we hire these days.
