Crisis
Short of a terrorist attack or your company being bought up and all your employees laid off, imagine a crisis that might occur at your company (or a company you would like to be employed by). It could be tampering of a specific product, a major chemical spill, an employee death because of faulty machinery, or something else.
Explain what your imaginary crisis is in some detail. As your company's chief public relations person, once you are aware of the crisis, whom would you notify within the organization about it and how would you notify them (use job titles, not actual names)? What would you ask them to do? Then discuss what information you would want the public to know during the first few hours after the crisis occurs. Similarly, what information would you want your employees to know?
How would you gather the information? How would you convey the information to both the public and your employees? Who would be your official public spokesperson (use the job title, not actual name)? Why? Who would be your official spokesperson to employees? Why? What are the two or three key messages you would want your spokesperson(s) to deliver to the public and employees? Would each target audience get different messages? What would you do if you found out that reporters are asking employees for their comments about the crisis?
