Three former leaders of a mobbed-up union were convicted on all counts yesterday for extorting payments from business owners to ensure labor peace.

Anthony Fazio Sr., his son Anthony Jr., and nephew John Fazio face maximum prison terms ranging from 65 to 105 years for their crimes, which the feds say they committed from 1989 until their arrests last year.

The FBI says both Anthony Sr. and John Fazio have Genovese crime-family ties and allegedly got a mobster’s son a no-show job with United Food and Commercial Workers Local 348-S.
