I have an employee who, after a great pre-employment interview, has problems with the use of proper grammar even after, initially, being advised of the problem in private employment reviews and written evaluations. She has been advised to seek assistance with her grammar several times. What started out as a great prospect for a critical not-for-profit fund raising development team, has turned into an embarrassment with the donors we need to continue our mission.

We have formal performance reviews in place for all employees. We have multiple reviews of written communications between staff and donors. What we cannot control is spontaneous conversation between staff members and donors. There was absolutely no indication in multiple interviews that this was going to be a problem. We have advised tutoring, reading and other means to enhance her communication skills.

She now has difficulty putting in a full 40 hours a week due to "family" issues and it is affecting our development team. She is well salaried and I have made numerous attempts to advise her. What do I do?
