Once a provisional agreement has been reached between the employer and the union representatives, each member of the union has the opportunity to vote in favour of acceptance or rejection. If at least 50% of the union members who actually vote accept the agreement, it becomes legally binding. If union members do not accept the agreement, the employer and union representatives can continue negotiations. Alternatively, the union may call for a strike vote. A strike vote must also receive at least 50% support from voters. Very rarely, where a union cannot obtain ratification or strike authorization, it will give up its right to represent workers. A collective agreement (CBA) is a written legal contract between an employer and a union representing workers. The KNA is the result of a broad negotiation process between the parties on issues such as wages, working time and working conditions. . . .
