The number of managerial sackings in the top four divisions has reached its highest level in 13 years, according to the League Managers' Association (LMA). Its latest figures show 47 bosses have been dismissed so far this campaign, the second highest level since the Premier League began 21 seasons ago.
A record 20 Championship managers have been sacked this season with 150 coaches also losing their jobs overall.
LMA chief Richard Bevan said the figures were "very concerning".
"We don't want owners thinking this a casino," he told BBC Sport.
"It's not stick or twist, sack the manager and let's see if we can get up a couple of places into the play-offs."
Five Premier League bosses have been fired this campaign, compared with the 12 sacked last season, which Bevan said was positive.
Twelve managers have lost their jobs in League One, with 10 in League Two.
