Jayshree Housekeeping is about the building and household work is about the house. Someone who is working on a permit means that they have a fixed job and nobody can ask them to leave their job till the day they die. They can continue working till they die or as long as they want to. And they will get pension even if they stay home. Other kinds of jobs in the SGNP are on a temporary basis. One will have to leave immediately when asked and then one has to keep searching for a job again.
