How do you politely ask a board member to resign.

What kind of board and are you also a member of the board? There just aren't many ways to ask some one to give up something they do not want to give it. More details may help

Politely? Guess you take them out to dinner or lunch and ask them privately.

Hi, Landr!

Would you mind sharing what the board member has done to warrant being asked to resign, please?

Also, what kind of board is this and how many people are on the board?

Thanks!
