I do not like the burka. I think it is a garment of oppression proven by how women fought against it in the 1970s in Iran when they were wearing the same garments of Western culture but were forced into burkas. I am shocked that women would choose to wear them.  That said I would be okay with them wearing them provided their faces are not covered.  That is too much. Employees have the right to see who is approaching them.  Employers or the government should not put employees at risk.  Students especially kids with learning disabilities have the right to see the face of their teachers. Non verbal (or facial features) are 80% of communication so when you can't see a person's face when they are speaking you can't always interpret it correctly or the way it was meant. There are students with Nonverbal learning disabilities that need that extra connection.
