Bernard (Rambo) Gauthier was sentenced Tuesday at the courthouse in Sept-Iles, Que..
A Quebec court judge convicted Gauthier in December of intimidating construction entrepreneur Frederic Boucher during a work conflict in June 2013.
The judge concluded that Boucher had grounds to fear for his safety after Gauthier paid him a visit.
The sentence will allow Gauthier avoid jail time, but he will have to abide by certain conditions.
He will also be able to keep his union position.
Gauthier's name surfaced during Quebec's corruption inquiry as the commission heard about threats and extortion on the province's North Shore.
A spokesman for the Quebec Federation of Labour's construction wing says Gauthier is happy with the sentence.Suggest a correction
