A report from the League Managers Association has claimed that club's in the Premier League and Football League spent almost £100m in changing bosses last season.
According to figures released by the LMA, the cost of compensation, legal fees and 'double contracts' amounted to £99m.
The findings have also showed that clubs tend to part company with their managers in October.
"We want to move away from managers being judged on their last three results," LMA chief executive Richard Bevan told BBC Sport.
"In fact, when results take a downturn that is when the club should support its manager even more, not jump for the quick fix."
The figure of £99m would have been higher had agents fees and the cost of sacking and replacing a manager's backroom team been taken into account.
