If we look at the contents of the complaint, which include "taking all her photographs & CV from her system to his folder on his PC, commenting on what she must or must not wear, how she looks today besides following her to the parking lot," the complaint certainly points towards misconduct on the part of the male employee, if proved. Based on the complaint, I feel there is no harm in setting up a domestic enquiry or, at least, a fact-finding enquiry. Such an enquiry, which would involve the examination of witnesses, is likely to shed more light on the subject as those witnesses would normally be colleagues on both sides who would, in all likelihood, have important but undisclosed inputs to share with the enquiry committee. At the end of the day, a conclusion would hopefully be reached. And if nothing else, the enquiry following this complaint would certainly act as a deterrent as it would send a strong message among other staff not to indulge in such activities. This, in itself, would be a value addition in the whole process.
