This article talks about things like timesheet fudging and practices like 'buddy punching', not getting distracted by a news article here or there, or getting a non-work phone call between the hours of 9 am and 5 pm
Given that companies typically want to maximally exploit their employees while paying the minimum wage they can, I don't really care about employees doing a little exploiting in the other direction.
