League Managers' Association chief executive Richard Bevan has slammed the "embarrassing" number of managers axed this season.
Championship side Blackburn dismissed Michael Appleton on Tuesday - their third permanent boss this term - and Stevenage parted company with Gary Smith on Wednesday to take the total to 33 axed since August, with the number rising to 103 when the backroom team are included.
"That's over 100 people, 100 managers, 100 families," Bevan told BBC Radio 4's 'Today' programme.
"I'm not sure where the arrogance of football comes from that we don't have to behave as any other industry. It's embarrassing for the game that all of those sackings are unfair dismissals. The volatility is undermining the profession.
"We need to work as a group - the Premier League, the Football League, the Professional Footballers' Association, the LMA - to ensure that we have better training not only for managers, but also an understanding of how you run a football club."
In regards to Blackburn, who have also seen the departures of Steve Kean and Henning Berg earlier this season, Bevan believes a communication breakdown is key to premature dismissals.
"Everything in business is about communication," Bevan continued. "Michael told me he had no conversation at all during his tenure since January with the Indian representative running the club.
"He's got 20 players on the injury bench. What he needed was support, not a letter of sacking. To have five managers [including caretakers] this season is nonsense.
"Blackburn need to look very hard into stability, they need to look at communication with the fans and they need to look very hard into how they can invest in personnel, look medium term. That's the only way they're going to climb up the table."
