Many players came out heavily in support of Vasek Pospisil after he revealed tensions between the ATP Tour and the PTPA.
During his Miami Open first round defeat to Mackenzie McDonald, emotion got the better of Pospisil but not due to anything that happened on court.
At the changeover between sets, Pospisil spoke to the umpire, telling him the ATP chairman Andrea Gaudenzi 'screamed' at him for over an hour in a meeting the previous day.
World number one Novak Djokovic, who co-founded the PTPA with Pospisil has come out in support of the Canadian, and he is not alone.
"Player unity is needed now more than ever. Voices need to be heard, respected and acknowledged," Milos Raonic tweeted. "Don’t try to silence them, but work with them."
Other players also showed support for Pospisil and urged the ATP to start listening, led by US number one John Isner.
"What happened with Vasek Pospisil was unfortunate," said Isner.
"Emotions got the best of him, and unfortunately, that happens sometimes.
"Fact remains that he's spent countless hours fighting on behalf of his colleagues on the ATP Tour. Better days ahead for Vasek and the players."
Veteran Ivo Karlovic also came down strongly on the side of Pospisil, and insisted the incident showed how much independent representation was needed in tennis.
"Unfortunate what happened on court with Pospisil," Karlovic said. "I was not at the meeting but, from what I heard from players that were there, it’s now more obvious than ever that we need a players only association."
Three-time Grand Slam doubles champion Rajeev Ram also showed his support, tweeting that what happened 'is not right', while Ryan Harrison said it 'was time the players' voices were heard'.
