POLL: Ban on cleaning window exteriors?

Should domestic workers be banned from cleaning the outside of windows?
A total ban is what a migrant workers group, the Humanitarian Organisation for Migration Economics (HOME), is calling for to prevent future mishaps from happening.
Already seven domestic workers, all Indonesian, have fallen to their deaths so far this year.
The latest casualty was a maid in her thirties who was found dead at the foot of a Punggol flat last Thursday.
HOME is hoping to gather 300 individually written letters to send to the Ministry of Manpower and has so far received 50 from Indonesian maids during an event on Sunday.
Do you think domestic workers should be banned from cleaning window exteriors?
