Well here it goes,

I started out in customer support (A lot of stuff to tell here).

1.
One of my colleagues would come to work drunk, like every day he would smell of boze (the hard stuff 80%+). When a customer got on his nerves he endet the call and threw his Keyboard across the room. He worked in the company 3+ Years after I left.

2. Another colleague would connect to his Personal Computer at his home and play WoW while at work ( Allthough the man was a genius with a lot of free time, until a new task was assigned to him)

3. My Boss at the time did some really shitty things. I worked 17 hour days (while I was 18) for a week, and at the end of the week he shredded the accrued overtime with some Bullshit Explanation. (I did not stay long after this shitshow happened).

4. A dispatcher who sent our technicians out scheduled their tasks so that they were on the road for weeks and did not see their families. This led to a very strong turnover among technicians.

And yes, this company still operates today.
