The League Managers' Association has dismissed the idea of a transfer window for their members because of fears it would make them even more vulnerable.
A total of 19 managers have left their jobs already this season, according to the organisation, and only two resigned.
Just last week there were seven departures in the space of eight days across England's four divisions. Martin Jol leaving Fulham and Owen Coyle's exit from Wigan were among the most high-profile changes.
But Richard Bevan, the LMA chief executive, wants to empower managers to work more closely with club chairmen and encourage better communication rather than resorting to the radical idea of introducing a new transfer window.
"It is not just the 19 managers, last week was a pretty heavy week," he told Sky Sports News. "We lost, in total, 27 people and that is a lot of families. We have 48 clubs who have a manager who has been in his job for less than a year.
"We need to help our managers. They have got to perform off the pitch as well as on it. Around 30 per cent of managers are getting sacked because of relationships.
"I'm up for discussing anything which will increase that tenure and help the club as well as the managers and coaches.
"But I'm not so sure about transfer windows. I'm not sure the transfer window works at the moment and one for managers may actually increase the number of sackings."
Statistics collated for Sky Sports News show dismissals have little impact on results anyway.
Research shows that over the last five years a new manager has only improved results by an average of 0.5 points per game in the first four matches after being appointed.
However, it drops to an average of just 0.1 point per game over 30 matches, showing there is little long-term benefit for a team's performance.
Bevan added: "Three of the longest-serving managers are top of their leagues - Arsene Wenger at Arsenal, Russell Slade at Leyton Orient and Chris Wilder with Oxford United - and that sends out a good message."
