As far as I can make out there are 2 things......
1] There is a large care home sector here and many work in that sector.
2] My impression (and it is only an impression) is that the Isle of Man people as a whole are happy to have Filipinos on the island for their qualities. I am certain that there are nowhere near as many from other countries in South East Asia and there are few from other parts of Asia. It can be like walking down a street in Manila sometimes, where the main shops are.............just a few degrees cooler thats all.
