Who did Elie work on an electrical plant with?

After a medical examination, Eliezer is randomly put in the orchestra block and befriends some musicians, who tell him that he has been placed in a good unit. All he has to do is count bolts and bulbs in an electrical warehouse, and he gets his father transferred to his unit. The only real hazard is Idek, the Kapo, who sometimes flies into violent rages. Eliezer befriends two Czech brothers named Yossi and Tibi. He hums Zionist chants and discusses Palestine with them, and they all plan to leave Europe as soon as they are liberated.
