I have a maid that works for me 4 days per week, from 8am to 2pm, and she gets paid RD$3,500 twice per month. I pay her vacation pay (paid out, she does not want to take it) and one month X-mas salary.
One note, as I said on other posts, be very careful with severance pay when 1) the house is on a company name or b) you have occasional or regular vacation rentals in this house = this can mean, in the eyes of the labour court, that your house is running as a business and not as a private residence, so your maid is then considered an 'employee' (with liquidation pay rights) and not a 'domestic helper.'
Keep in mind that when you get sued for severance pay, the other lawyer will throw in 'unpaid overtime' and other sheninagans in order to get the law suit up two or three times the amount of the severance pay.
