Final answer:
After gaining recognition, the union president would pursue collective bargaining to negotiate the terms and conditions of employment with the employer, aiming to formalize an agreement without immediate strike actions.
Step-by-step explanation:
Once the Prairie Clerical Workers Union has received recognition as a bargaining agent for a group of employees, the union president would most likely undertake substantive collective bargaining efforts to secure a collective agreement. This involves a process wherein the union and the employer's representatives meet to negotiate a mutually acceptable set of terms and conditions of employment. The focus at this stage is on building a formal relationship through negotiations rather than engaging in any form of strike action or further union certifications, as the latter is already established in the recognition of the union.
