> They have zero avenue for support when they face abuse whether physical, sexual or emotional.

That is not true at all. Singapore is a country of law and order.

> visas in places like these ask you to leave immediately if you get quit or fired from a job.

They have been invited to a country as a temporary worker to do a specific job.

Saying you have to go home if you get fired is not inhuman.

I have worked offshore and had my contract canceled - it sucks but it’s not inhuman.
