Union density

The union density or union membership rate conveys the number of trade union members who are employees as a percentage of the total number of employees in a given industry or country.^[1] This is normally lower than collective agreement coverage rate, which refers to all people whose terms of work are collectively negotiated. Trade unions bargain with employers to improve pay, conditions, and decision-making in workplaces; higher rates of union density within an industry or country will generally indicate higher levels of trade union bargaining power, lower rates of density will indicate less bargaining power.^[1]
