How could Jim gather employees$$ honest opinions of diversity in the company?

option $1$

Conduct a series of focus groups with employees using an outside moderator. Assure employees that all responses will be confidential.

option $2$

Give managers another survey to give to employees and have it clearly noted on the survey form that all responses are anonymous. When the surveys are filled out, have managers collect them and give them to Jim in a sealed envelope.

option $3$

Have a brown bag lunch with each department so employees can openly talk about any diversity issues they feel are important.
