Final answer:
The most likely explanation for the worker's poor performance is that she isn't treated as an adult at work, which relates to Theory X management that does not provide autonomy or respect the individual's maturity, causing reduced engagement and satisfaction.
Step-by-step explanation:
According to Chris Argyris' theories on management and organizational structure, the worker's poor performance could be attributed to being treated in a manner that does not respect her maturity or individuality, which aligns with Theory X management approach. Argyris believed that when employees, like the worker in the scenario, are not treated as adults and are not given a chance to be responsible and self-directed, their engagement and performance can suffer. Theory X assumes that workers are inherently lazy and require strict supervision and control, while Theory Y assumes that employees are naturally motivated and seek fulfillment and satisfaction in their work.
Given the information about the worker being a responsible parent, making car payments, and active in local organizations, it suggests that outside of work, she demonstrates responsibility and engagement in her activities. However, at work, if she is not given the autonomy to make decisions and treated as a mature adult (which is similar to the language in option (a)), it can lead to poor performance and dissatisfaction. With Theory Y assumptions, managers believe that workers like her would thrive under conditions where they are valued and can contribute meaningly.
