Viktor Fejes, 28, of Staincliffe, climbed 20ft up a tree in parkland off Track Road and hanged himself.
An inquest in Bradford was told Fejes was brought to Britain and put to work in local bed factories by a brutal workmaster.
Mr Fejes was moved to Newcastle after Orsos was convicted but later returned to Batley to work.
Deputy coroner Dr Dominic Bell heard how Mr Fejes spoke to his mother on October 22 and was found hanging from a tree the next morning.
Dr Bell said at the time Mr Fejes went to the park there would have been no-one around to help.
