Employees calling out over the stupidest things is my biggest pet peeves of being a manager.
We have a very small staff and when one person calls out it can affect every one of us.
I also have to deal with the employees who refuse to come in on their days off to help cover when asked. These, of course, will be the same people who complain about their hours and how little money they make.
I sacrifice everything for my job (sadly- maybe I shouldn't admit it) but I will always take up the slack. I've worked 10+ hour days, gone many days at a time without a day off and very very rarely call in sick.
In fact, I kept showing up to work because I didn't want to cause problems for anyone else when I had phenumonia and a collapsed lung, which then sent me to the hospital for two weeks.
Ok, I'm an idiot, but I have a huge work ethic and it pisses me off when someone calls in with a tummy ache or with a case of lazy.
