Answer:
A trade union is an association of workers from certain professions for the purpose of promoting common interests related to their work. The work of trade unions is thus usually about work-related issues such as wages, job security, leisure time, but also about things like education and job titles where applicable. Trade unions negotiate wages and conditions with employers in wage agreements they make on behalf of their unions. Thus, these unions seek to maximize the rights of workers in their work spaces, trying to ensure that employers respect the rights of their employees without restriction of any kind.
