The role of supervisor is a key role. The relationship between the supervisor and the students should be healthy.
In this context, in India, there is a lot of difference between male and female students. If a male supervisor frequently holds meetings outside of the workplace, male students can participate without any fear while female students cannot.
How does a female student reject the invitations of a male supervisor to meet outside of the workplace (such as in the supervisor's home)? The purpose of the invitation is to discuss the developments or updates in research.
Many incidents like 1,2,3 etc., have occurred and hence female students have to think about their safety but at the same time they still have to work around the supervisor's workload. (He may not get time during his working hours to review his scholar's progress.)
