San Francisco (CNN Business) Kickstarter employees voted to unionize on Tuesday, making the crowd-funding platform one of the first in the tech industry with a union.

The workers voted to unionize by a margin of 46 to 37 in an election held by the National Labor Relations Board. The workers will be affiliated with a chapter of the Office and Professional Employees International Union (OPEIU)." The union comprises 85 Kickstarter employees including engineers, analysts, designers and customer support specialists.

"Kickstarter employees felt their employer, a public benefit corporation, should live up to the foundational progressive values it espouses by ensuring trust and transparency from management, guaranteeing equal pay for equal work, implementing more inclusive hiring practices and giving employees a voice in the decision-making process," OPEIU said in a statement.

The decision to unionize came after several months of conflict between the company and its workers, with two employees fired in September who say their termination was linked directly to their union organizing efforts.

Clarissa Redwine, one of the fired employees, told CNN Business that she began to receive "unprecedented negative feedback" from Kickstarter management a few weeks after becoming a public union organizer last year, despite a good performance record.
