Final answer:
Complacency about professional standards is indeed a common reason for unprofessional conduct at work and can lead to job loss if not corrected.
Step-by-step explanation:
True, complacency about professional standards is a common cause of unprofessional conduct in the workplace. Many employees initially adhere to workplace rules and exhibit professional behavior; however, as they settle into their roles, there's a risk of becoming too comfortable. This can lead to a relaxation of professional standards and, consequently, unprofessional behavior which can be costly, potentially resulting in job loss. It is important for employees to continually maintain a high level of professionalism to ensure they meet the basic expectations of their role and exhibit good workplace conduct.
