Is anyone able to help me with the questions below pertaining to business law. (agencies, partnerships and employment/unions)

1. How does a union become the exclusive bargaining agent for a group of workers, and what are the unions duties toward its members?

2. What happens to a general partnership upon the death of a partner?

3. How can an agent, rather than the principal, become liable on a contract signed by the agent for the principal?
