Mill Worker

 is a Fallout 3 achievement that is added to the game in The Pitt downloadable content pack. It is granted for collecting 100 Steel Ingots.

Steel Ingots are found in the Steelyard, the Abandoned Area and the Supply Plant. 10 must be obtained as part of the Unsafe Working Conditions quest. Ingots are returned to Everett in The Mill. He will give the Wanderer an item for every 10 ingots found. In order to get the achievement, you must bring all 100 ingots to Everett.

Bugs

 * In some cases Everett won't go into the Mill where you have to give him the ingots preventing you from finishing the quest.
 * Sometimes Everett won't even speak to you at all, which also prevents you from finishing the quest.
 * If the last few ingots are presented on their own, Everett may not accept them (unconfirmed)

Trivia

 * Once you have collected all 100 Steel Ingots, Everett will say "Yup, guess you got every last one out there. You're one hell of a steeler, kid." "Steeler" is a common name for a worker in a steel yard. It also could be a reference to the Pittsburgh Steelers (whose team name is also a similar reference to steel yard workers).
 * Everett also makes a reference to someone who travelled 'from here to Monroeville.' Monroeville, Pennsylvania is the city where Pittsburgh native George A. Romero filmed the classic 1978 horror film Dawn of the Dead.
