Answer:
The sender is using an indirect approach in an unethical manner.
Explanation:
In order to dispense transparency in the functioning of the management, it is necessary that an issue as crucial as laying off of 52 workers is communicated to the workers directly by the sender.
Sending an indirect message would be termed as unethical majorly because that would leave the workers in distress and the workers would also be confused about the authenticity of the news.
