Raising awareness of a new occupational hygiene policy across a large and diverse workforce requires a coordinated and multi-channel communication strategy. From a strategic communication management perspective, an integrated approach using both printed and digital media is the most effective option because it maximizes reach, repetition, and message reinforcement across different employee segments.

In an organization with 12,000 employees, reliance on a single communication tool is unlikely to be sufficient. Employees vary in their roles, locations, access to technology, and information consumption habits. An integrated approach acknowledges this diversity by combining tools such as posters, emails, intranet content, digital signage, briefings, and printed materials. This ensures that key messages are encountered multiple times and through trusted channels, increasing the likelihood of awareness and comprehension.

Strategic communication emphasizes message consistency across platforms. An integrated approach allows the same core policy message to be adapted in format while remaining aligned in content. Visual materials can provide quick reminders in workspaces, while digital media can offer more detailed explanations, FAQs, and updates. This layered communication structure supports both initial awareness and ongoing reinforcement.

The other options are limited in scope and effectiveness. A memorandum or staff-meeting discussion depends heavily on managerial follow-through and may not reach all employees consistently. Intranet articles require employees to actively seek information, which reduces exposure. A poster campaign alone raises visibility but lacks depth and interactivity.

Effective policy communication is not about choosing a single channel, but about orchestrating multiple channels to work together strategically. Therefore, an integrated approach using printed and digital media best reflects strategic communication management principles and is most likely to achieve broad awareness and understanding of the new hygiene policy.
