Bury have parted company with manager Chris Casper and director of football Keith Alexander with immediate effect following a dismal nine-match winless streak in all competitions.
Casper had admitted after Saturday's 3-0 defeat at Darlington that his job was under threat, and the Shakers board has acted now to stop the club's plunge towards the relegation zone.
A statement on the club's official website read: "This decision has come at a difficult time for the club but it was felt that it had to be taken earlier, rather than later.
"Unfortunately the management team of Chris Casper and Keith Alexander has lost the confidence of a large majority of the fans, and the directors have taken this decision for the benefit of Bury FC."
The pressure had been mounting on the duo ever since the board warned them last month that results needed to improve or they would be axed.
They said after the defeat to Dagenham & Redbridge: "The board has explained to Keith and Chris that the fans and the club expect improvement in future results and they will be monitoring the situation on a game-to-game basis."
Casper had been in charge at Gigg Lane since September 2005, while Alexander was appointed to his position eight months ago.
