The Austrian met his players at the club's training ground on Sunday, less than 24 hours after warning that a sixth managerial appointment in just over a year could follow if the squad failed to buy into his demands.
The meeting was intended to address the reaction to his comments, with the response understood to have been positive and supportive. Forest's players accept that their collective performances must improve, but there remains confidence within the dressing room that results can turn under Glasner.
The club are in the relegation zone after losing four of their last five Premier League matches, including Saturday's 2-0 defeat at Brentford. Glasner had made clear that he believed he had been too accommodating since taking charge and intended to change his approach.
"I feel I could see a few things from day number one. I feel now maybe I made too many compromises in some stuff, and it's always compromises," he said after the Brentford defeat.
"It's a clear way. I will tell [the players] what we want to do, what we have to do, and if the players buy in, I think we can have a turnaround and, if not, the sixth manager [since the start of last season] will come in."
Glasner also insisted that changes would extend beyond the playing squad, arguing that Forest needed to rebuild from the bottom to the top rather than repeat the cycle of managerial dismissals that has characterised recent seasons.
Despite the poor league position, the club's hierarchy are understood to support the manager and welcome his determination to address the problems. There is no indication that owner Evangelos Marinakis is considering another change, with the intention being to give Glasner the opportunity to establish greater stability.
Forest's underlying performance figures have also offered encouragement. They rank third in the Premier League's expected-points table, while sitting second for expected goals against and fifth for expected goals for.
Those numbers suggest their results have not reflected the quality of their performances, although there is an acceptance that improved chance creation must translate into victories. Forest have managed only one league win under Glasner so far.
Former manager Sean Dyche has also expressed sympathy for the Austrian, drawing a comparison with his own departure after Forest struggled to convert promising attacking statistics into goals.
Dyche wrote on social media: "Nottingham Forest are still finding the goals hard to come by. And I had it along with my staff, we scored but nowhere near what the metrics were telling us. So not enough to stay in our job?"
He added: "I hope Oliver is given more time and the fans stay with him and the players stand up and be counted."
Nottingham Forest now face Manchester City at the City Ground, with Glasner seeking an immediate response before the international break.
