But amongst the seemingly non-stop revolving managerial doors are long-serving managers who have built long-lasting legacies and written themselves into fan folklore.
We looked at the longest running tenures within the National League and found that the ten longest serving managers have served their clubs for a combined period of over 85 years at the helm.
Jason Ainsley takes top spot having been manager at Spennymoor Town for just over 11 years but has also spent most of his life at the club.
He’s been player, captain and assistant at Moors in a spell that dates back to 1989.
This current season will be his twelfth in charge having won five titles and an FA Vase in 2013.
In 2008, Paul Doswell joined Sutton United and is now the third longest serving manager in the National League.
Lee Bradbury is taking his Havant and Waterlooville side on another big journey this season as they compete in the top level of non-league for the first time.
He’s spent just short of six years in the Westleigh Park hotseat.
