2. Design a feedback action plan for delivering constructive feedback associated with a non-routine change to your employees. Provide a specific example of such a change.
3. Evaluate and assess the effectiveness of the channels used in the communication of this change.
4. Discuss two important ethical principles that the organisation considers to be important components of the organisational culture.
5. Highlight the most challenging stage of reactions that employees go through when confronted with the above-mentioned change, and provide a rational explanation, as a communication manager, to convince them to accept the change.
