I have been myself a high level MTG judge for several years, judging events in Japan, US and Europe. I know several of the people in this action.
Most of them could almost been considered as professional judges, not only because they judged high level events (profesionnal events, continental and world championships) but also of their work outside "floor judging". High level judges are required to be leaders, teachers and for some of them, active workers on the policies that judges are to enforce. This part of the job is not even taken into consideration in this class action.
I have myself been paid with shiny cards that I was able to sell for several hundreds of $ just 5 minutes after receiving them.
My worst tournament had the following schedule :
Friday : I helped for the set-up of the venue, the computer configuration and I took registration of players from 6PM to 10PM.
Saturday : Arrived at the venue at 7AM for pre-event meeting. I was the Scorekeeper of the event at this time, registering all results and providing pairing of the new rounds ... We faced several computer issues during the day and the tournament finished at 2AM in the morning. During this time, all judges worked on the complete duration (no shift at this time) with at most 1 real break for 19 hours. Personnaly I had additional works after the tournament ending for the day, I got to my hotel room at 5AM to wake up at 7AM.
Sunday : Arrived at the venue at 8AM, day was long again and the finals completed at 11PM. Some clean-up later and debriefing, it was 1AM.
It was an awful schedule, and I was quite lucky to be sitting behind a desk. Friends of mine were not that lucky.
I have been paid 12 boxes of product, that was worth of 12 * $90 at this time plus $200 worth of limited magic judge cards. I was one of the most fairly paid (most of the judges got 3 or 4 boxes).
I think not one judge who has ever work on a Grand Prix will tell you that he/she was a "volunteer".
But why the class action? Because of WotC. WotC management of the judges is garbage. It is toughier to become a judge than getting a basic job, the requirements are hard, especially if you want to progress in the hierarchy. But you don't have anyn contract with WotC, if at any point you express an opinion that WotC disapproves you may be terminated of your judge certification.
A close friend of mine was at the top level of the judge community (Level 5, max level). He disapproved some policies that were worked on at this time. At some point he expressed publicly his disagreement. Within 24h, he received an email entitled "Welcome to Level 0".
This way of treating judges is quite common for them, and they have years of HR managment to demote people disagrreing with them.
Guess what, I think all of the plaintiffs here have been treated this way (for some I know for sure, but I don't know all of them). So this is basic grudge and revenge. Is this moral?
Perhaps not, they were part of the system and probably managed to profit from it. But then WotC screws you. I think that's fair to try to screw them.
Regards.
