Mike Williamson cited Carlisle United’s long-standing losing “culture” as he reflected on the Blues’ woeful defeat to Swindon Town.
The Cumbrians collapsed to a 5-1 defeat to the Robins as fans chanted for Williamson to go.
The head coach said any such decisions were out of his control and that he was “not interested” in addressing questions about his future.
Instead he suggested the Blues were still struggling under the weight of their recent era of struggle – despite a huge influx of new signings.
Carlisle, rock bottom of League Two, have only take two points from all the games in which they have gone behind this season.
“It says that the group, the club, have had a really hard couple of years and a knock feels like a sledgehammer,” Williamson told the News & Star.
“We've come in and we're doing everything we possibly can to try and change that, but it's not easy.
“The mentality that we're trying to build and create here is carrying bad, difficult feelings in the game.
“So small setbacks feel insurmountable, but for me the lads' effort…they're fighting and that's all I can ask for.”
Carlisle shipped five goals at home in the league for the first time since August 2013 as Ian Holloway’s visitors ran riot.
Dan Butterworth’s first-half goal against his former club came ahead of a second-half landslide as the Robins won a fourth game in a row.

Asked why United should be so brittle in the face of a setback given all the new players recently signed – they have brought in 11 during the transfer window so far – Williamson said: “Because it's the environment, it's the culture, it's everything.
“I'm not blaming anyone, I'm blaming myself. So there's zero blame for any of the older players, any of the new players, anyone but myself.
“But the fact is that we're on that front foot and we're being aggressive, we then come off and then we concede a sloppy goal and then, in the second half, a couple of minutes into it, we concede another sloppy goal.
“So that's the reason why we're struggling to come back from setbacks, because we allow it to knock on.”
United had started the game brightly but that was soon overwhelmed by their bleak collapse.
On why they should go under to such an extent, Williamson said: “Individual moments that shape our feeling in the game take the wind out of our sails.
“Two direct goal kicks led to two goals, one came direct from a corner that wasn't touched and there were two counter-attacks.
“If you're giving these goals away you're not going to win any football match.”

Williamson refused to use Jordan Jones’ red card as an excuse for the outcome, even if he felt the dismissal was harsh.
The wing-back received two separate yellow cards for diving from referee Ross Joyce.
“For me, there's minimal contact, but there's contact. He's going at full tilt, he knocks it, there is contact, he goes down,” said Williamson.
“The referee, for me, makes a decision which I don't agree with. At the minute, these anomalies are happening. It's not the main narrative that we're sat here talking about, but it is one.”
On how much or little he felt the sending-off affected the game, he added: “It doesn't matter, does it? It doesn't matter what I feel.
“Ultimately, it takes the wind out of your sails because you're a man short and it minimises your chances of getting back into it. But the percentage [of how much it affected the outcome], it doesn't matter.”
