Russ Wilcox was critical of the decision which gave Chesterfield their equaliser as Scunthorpe's top-of-the-table clash ended in a 1-1 draw.
The Iron hit the front on 15 minutes when striker Sam Winnall tapped home the rebound after Paddy Madden's shot was spilled by visiting keeper Tommy Lee.
Chesterfield were handed a lifeline just before the break when Terry Hawkridge was adjudged to have taken Ritchie Humphreys down in the box.
Eoin Doyle made no mistake from the spot and 1-1 is how it stayed, giving Scunthorpe their fifth successive draw.
Wilcox felt his side were on the wrong end of a couple of calls as they failed to get the win that would have drawn them level with leaders Chesterfield.
"It was a modern day penalty, a soft one, there was not much contact," he declared.
"But we should not have allowed ourselves to get into a situation like that where we give the referee a decision to make.
"It was disappointing we did not get one in the second half when their player is all over David Mirfin at a corner. Anywhere else on the pitch and that is a foul."
Wilcox knows his side need to rediscover the winning habit if they are to realise their dream of automatic promotion.
"We go out there trying to win every game, as we have done in each of the 14 unbeaten games since I took over," he insisted.
"Like Chesterfield, we want to play open and attacking football but that is difficult to do in conditions like this.
"We went out to try and take three points from them but unfortunately could not quite achieve that.
"What my players are showing though is that they have a terrific work ethic and that is credit to them."
