Abstract
Workers' "voice" is traditionally expressed through unions, but union densities are now declining. The author reports on a survey of attitudes towards unions held by unionized and non-unionized workers in Bangladesh, Brazil, Hungary and Tanzania. She finds that relatively more unionized than non-unionized respondents thought positively of unions; and that union activity outside the formal economy and by women and younger workers was negligible. Even amongst union members, fewer than half thought positively of unions or trusted them (except in Bangladesh), and going to a union was only one of various preferred forms of action in case of dissatisfaction.
