Final answer:
Bernadette is overlooking the force of employee dissatisfaction and dissatisfaction with working conditions, as unions can have an impact by advocating for better wages and working conditions, and providing a platform for employee concerns.
Step-by-step explanation:
Bernadette, the chain's vice president of human resources, is overlooking the force of employee dissatisfaction and dissatisfaction with working conditions in her assessment of unions not having an impact on the company. While turnover is high and organizing campaigns are difficult due to the transient nature of part-time employment, unions can still have an impact by advocating for better wages and working conditions, and by providing a platform for employees to voice their concerns. Bernadette should consider that unions can address the issues of employee turnover and job insecurity, potentially leading to a more stable and content workforce.
