Final answer:
Managers can establish and maintain openness by encouraging active participation, foster trust by being open to feedback, and maintain honesty by leading by example.
Step-by-step explanation:
One practice that managers can introduce into the environment to establish and maintain openness is to encourage active participation.
Managers can create a space where employees feel comfortable speaking up in meetings, sharing ideas, and embracing new projects.
This practice promotes an open and collaborative culture in the workplace.
To foster trust, managers can be open to feedback and respond professionally to it.
When managers show that they are receptive to feedback and willing to make improvements based on it, it helps to build trust between managers and their team members.
In order to maintain honesty, managers can lead by example and demonstrate transparency in their communication and decision-making processes.
By openly sharing information and being straightforward, managers can create an environment of trust and honesty.
