Peterborough chairman Darragh MacAnthony says he will oversee interviews for a new manager in May.
A run of one win in five games under caretaker boss Dave Robertson has left Posh 10th in League One and struggling to reach the play-offs.
Robertson won his first four games after taking over in February following the dismissal of Darren Ferguson.
"Nobody has been ruled out and nobody has been guaranteed the job either," MacAnthony told the club website.
"The style and standard of football seen over the last four-plus games from the first team is nothing like how I want our club to play.
"Our current management team know my feelings on this and agree this isn't the Peterborough United way we have all come to know and love.
"The current management squad knows that I have not committed to them beyond the next five-plus games."
The Peterborough chairman continued: "They also are aware I will be travelling to the UK in May to oversee formal interviews, not just with them for the full-time position of manager, but with a shortlist of other candidates."

MacAnthony also plans to make changes to the playing squad during the summer.
"Every member of our first-team squad is playing for their own future," he added.
"As a group, as a team, they have been found out once too often this season and the lack of goals scored is a record in all the time I've owned the club.
"This will be addressed and fixed this summer and it will be interesting to see how many of our own players perform over the final games left in the season."
