What are your departmental policies regarding attendance? Coming in late? Leaving early? Not using the sign-out board? Disappearing for hours? Calling out at the last minute?
I have a more relaxed philosophy about such matters as long as all the works gets done and gets done well and on time. The problem is how do you respond to such issues when the work isn't getting done? Is it a matter of lack of motivation? Bad apples? Stan-hood?
