We have an employee who says they have allergies to another employees perfume. We have had some issues with this employee in the past and are not so sure that the perfume is an issue. None of the other employees say they have problems with the perfume this particular employee is wearing. I know we need to provide good working conditions but how far do we need to go to accomodate this complaint. The employee she is complaining about is a great employee and we sure don't want to lose her over this!
