sorry but this is not “bad treatment”.
Soap princesses are private contractors and when they don’t show up to work, their appointments are canceled.
Of course there is no paid time off.
I have always been treated excellently soap, for example I was free to exchange contact information with clients and it would not be monitored, the girl’s cut was more than half (have to pay “room rent fee” and pay for some of your own work tools, but others like the nuru gel are free) and gaijin tax went to the girls 100%.
But as a self employed person I would never dream of anyone financially supporting me when I’m sick. I guess there are ways to take out insurance for this as a self employed person/ contractor, but I don’t know if that’s a thing at all for people in the fuuzoku industry. I guess people who have their situation together have some savings, but if you are in the middle of paying off debts or supporting someone, you’re out of luck I guess.
But that’s not your employer’s responsibility.
Generally if there are no customers being serviced, there is no salary for the girls.
I have heard of some delivery health that have a “guaranteed income” of 10.000 a day even if there are no customers. But the requirement for that is that you have to be at the shop on that day, so definitely no paid sick leave either!
