Whites moved nine points clear of the drop zone following a goalless draw at Crabble on Saturday.
In a game of few chances, Athletic held on to extend their unbeaten run in the National League to five matches.
Inih Effiong jinked through the visiting defence early on, however both he and teammate Alfie Pavey both tried to shoot at the same time and the ball rolled harmlessly through as a result of the mix-up.
Chesterfield, with seven changes from their 2-0 win against Dagenham & Redbridge last weekend, forced the first shot on target with home stopper turning away Jack McKay’s stinging volley.
Bobby-Joe Taylor’s swirling free-kick had Joe Anyon scrambling, but the ball flew over the visiting goalie’s far post.
Jai Reason’s long ball set Alfie Pavey clear, but Spireites skipper Will Evans recovered in time to make a last ditch challenge.
Stuart Lewis then sent a 25-yard effort into the side netting for Athletic.
Worgan then dived low to grab onto Marc-Antoine Fortune’s low drive following a one-two with Charlie Carter on the edge of the area and at the other end Mitch Brundle sent a piledriver just over.
Lewis sent another shot from distance over after Taylor’s free kick struck the Chesterfield wall and Fortune scuffed well wide from a right angle after Lee Shaw had played in the ball from out wide.
Dover’s best chance came midway through the second half.
Kevin Lokko headed Reason’s pinpoint delivery goalwards, only for the ball to cannon off both Pavey and Bedsente Gomis and away after both players tried to head on target.
Andrew Kiwomya blazed over from a few yards after Worgan’s parry from Fortune fell kindly for the substitute.
Kiwomya saw his shot strike Lokko and though Lawrence Maguire sent the rebound goalwards with venom from the edge of the box, Lokko bravely blocked the ball with his body to keep Dover’s clean sheet in tact.
Earlier, boss Andy Hessenthaler made one change to the side that started at Solihull last week, with Effiong replacing the injured Jamie Allen.
Whites are in National League action again next weekend when they travel to Barrow on Saturday 13th April, kick off 3 pm.
