Final answer:
Procedures do not necessarily have to be placed in manager/supervisor offices at all times but should be accessible. As an absolute requirement, the statement is false.
Step-by-step explanation:
When considering whether procedures must be placed in the manager/supervisor offices at all times, it's important to note that while there is no specific rule that mandates this universally, good business practice suggests that procedures should be accessible to those in managerial or supervisory roles to ensure consistency and compliance within an organization. However, procedures may also be kept in a common area or a digital format accessible to managers as needed. Hence, the statement can be considered false as an absolute requirement.
