A man who locked two Polish immigrants in his loft, using violence against them and controlling their ID documents, had been jailed.
One of the men was forced to work 20 hours a day making greetings cards.
Edward Zielinski, 42, of Birkin Avenue, Hyson Green, Nottingham, admitted two counts of modern slavery and was jailed for three years and four months.
Judge Gregory Dickinson QC told Zielinski he had treated the victims in a "thoroughly degrading way".
Sentencing him at Nottingham Crown Court, he added: "You made them live in squalor and took away their incomes."You took away their dignity as human beings, you fully exploited their vulnerability, you were able to brow beat and control them through threats and intimidation."
The offences took place between 31 May 2013 and 1 June 2017. Zielinski made the men work for little or no money. He would also force his victims to urinate in plastic bottles at night rather than wake him and his wife.
