Striker Shaun Harrad, who scored twice at the weekend as Town lost 4-2 to Bury to extend their winless streak to 15 games, revealed Johnson has called the squad in for extra training.
Harrad said: "I believe we can get out of this but all the lads are looking at the league table and thinking 'how are we here?'
"We trained on Sunday and we're in on our day off this week and that's fair enough - of course it is.
"We've got to look to get a result at the weekend somehow.
"There is a lot of frustration and anger from the fans and I fully understand that but we need them to support us as much as they can."
