What are the regulations governing the mixing of men and women in the workplace, especially when holding training courses that bring both sexes together to discuss work matters, or when conducting external interviews with families?

Unlawful mixing (Ikhtilat) refers to the gathering of men and women under one roof without adherence to Sharia regulations, such as physical contact, women not observing hijab, or their speaking in a soft, alluring manner. However, merely gathering while adhering to Sharia regulations to discuss work matters and the like is permissible. Similarly, conducting interviews with families is permissible if it is controlled by Sharia regulations.
