Final answer:
Displaying an educational diploma and awards indeed increases an individual's power due to nonsubstitutability, by providing proof of unique skills and qualifications that are hard to replace, enhancing the individual's indispensability in the workplace.
Step-by-step explanation:
Displaying an educational diploma and awards in the workplace can indeed increase an individual's power through the contingency of nonsubstitutability. The contingency of nonsubstitutability refers to the ability of an individual to possess unique skills or qualifications that are hard to replace. An educational diploma serves not only as proof of attaining a certain level of knowledge and skill but also signals to employers and colleagues that the individual has achieved a standard that is recognized and valued in the professional community. Awards and honors further reinforce this by indicating exceptional performance or recognition within a field. In essence, these credentials make an individual's contribution to the workplace less substitutable, enhancing their power.
The concept of credentialism, which is the emphasis on certificates or degrees to show that a person has a certain skill or has met certain job qualifications, also supports the idea that displaying educational achievements can increase individual power in the workplace. This is because such credentials are seen as tangible evidence of one's skills and achievements, potentially making them indispensable to the employer.
