He was convicted of stealing more than $600,000 of Local 98 money and using it for himself.
Prosecutors say Dougherty and co-defendant Brian Burrows, who was the union president at the time, used the funds for home renovations, meals, concerts and trips.
This is Dougherty's second felony conviction.
In 2021, he was found guilty for bribery, along with former city councilmember Bobby Henon.
The judge in another federal trial where Dougherty was charged with extortion declared a mistrial last week.
