Working in a call center in workforce management, we used to give consideration to "special cases" when it came to absenteeism. We then found that one of our employees had had 11 grand parents die that he had to go to a funeral for (I'll let you do the math on that one), but he would give the funeral program to a different workforce person every time so he flew under the radar for some time.
Another instance; we had one user who has severe medical issues; she wasn't at one year yet, so didn't qualify for FMLA and she needed consideration for absenteeism or she'd be terminated. In the short term, we gave her clearance and she was able to continue working. She then posted pictures of a trip to Las Vegas where she'd taken time off for her "medical issues".
Two instances of absolute clear cut times where as a company you should make considerations. Then you find out people are taking advantage and the minority ruin it for the majority. Riot can't afford to look at the world through colored glasses. it's black and white. Why spend money taking the time to find out who's telling the truth and who's lying? Keep it sterile and anyone who leaves a game, regardless of the reason, get's punished.
