The average tenure of a manager in the professional game in England has dropped to just 1.23 years - with the Championship the hardest league in which to keep your job.
The League Managers' Association has revealed that in the Championship, where there were 20 dismissals in the recently-completed season, the average spell in charge is just 0.86 years.
There were 47 manager dismissals in the 2014-15 season, the most since the 2001-02 campaign when 53 were sacked.
Arsene Wenger continues to buck the trend, having managed Arsenal for 18.67 years and 1,065 matches.
LMA chief executive Richard Bevan said in the end of season review: "The numbers only serve to highlight that the game continues to present an increasingly more complex and volatile working environment for all the professional practitioners: the players, coaches and managers.
"If we are to see a significant change in the statistics within this report then the game and its leaders need to take a longer-term view and build stability."
Bevan, who highlights "short-termism" as one of the factors behind the changes, says 17 of the dismissed bosses were first-time managers who may find it difficult to manage again and more than 150 coaches lost jobs as a consequence of managerial changes.
There were 64 managerial changes up until May 31, 2015, with 17 resignations.
The 47 dismissals is 10 more than in the 2013-14 season and featured five in the Premier League, 20 in the Championship, 12 in League One and 10 in League Two.
The average term for a Premier League boss is 1.8 years, which is higher than in the other three divisions: Championship (0.86), League One (1.41), League Two (1.44).
The Premier League also has the highest average tenure of all current managers with 2.36 years. Championship (1.14), League One (1.44), League Two (1.67).
The next longest-serving boss after Wenger is Exeter's Paul Tisdale, who has been in charge for 8.93 years. Other Premier League bosses in the top 10 are Leicester's Nigel Pearson (3.54) and Liverpool's Brendan Rodgers (3.0), who are eighth and 10th, respectively.
