http://ftw.usatoday.com/2017/01/mino...t-kyle-johnsonJohnson is among four active minor league players attempting to join a lawsuit against Major League Baseball and its teams, and he's the first active player involved in the case to speak about it publicly. Spearheaded by attorney and former minor leaguer Garrett Broshuis and first filed in February of 2014, the suit currently includes 41 named plaintiffs and is awaiting a second ruling on class-action certification before it can head toward a trial. It seeks to apply the terms of the Fair Labor Standards Act — i.e. minimum wage — to minor league players, who earn as little as $1100 a month at the rookie level, only get paid during the season, and do not receive overtime pay.
