Adrian Smith had published that churches should not host gay weddings and that they are "an equality too far".
As a result, he was deemed by the Trafford Housing Trust to be wrong to express such views and received a 40% salary cut, according to The AP.
The company's code of conduct warns against expressing religious or political opinions that could offend or upset colleagues.
However, the High Court ruled in Smith's favour, as the judge said last Friday (November 16) that he had done "nothing wrong" and was unfairly punished.
Trafford Housing Trust "accepted" the verdict, while Smith was happy that Britain is a "free country where people have freedom of speech".
Gay rights campaigner Peter Tatchell agreed with the court's ruling, saying: "In a democratic society, Adrian has a right to express his point of view, even if it is misguided and wrong."
