Explanation:

Vulnerability in research suggests that certain persons, by participating in a research, are unable to protect their own interests and as such, may suffer certain negative consequences as a result of the research.

Such people may not be able to refuse to participate in the research (for example workers in an organization suffer from research vulnerability).

Employers may feel that a research is beneficial to an organization and as such, put some pressure on workers to participate in a research that may end up being detrimental to the workers' growth prospect in the organization.

Unions may also push workers to participate in a research to gain certain benefits.
