Sham Shuk-ching will get a pay rise of HK$492 next month on top of her salary of HK$6,200 thanks to the minimum wage legislation.
At present, Sham, 34, works eight hours a day from Monday to Friday and four hours on alternative Saturdays as an assistant to Tuen Mun district councillor So Shiu-shing.
Together with a colleague, she helps So represent the Sham Shing constituency, which has about 20,000 residents.
On a recent Saturday at the Sham Shing Estate office, she could be seen managing documents on a computer, searching for council papers, files and pictures for her boss, answering residents questions and cleaning.
Sometimes Sham attends nighttime meetings with residents and corporate owners after the tenants have finished work.
As neither she nor her boss knew whether her pay would be in line with the minimum wage law, Sham called the Labour Department to check. They calculated it would be safest to raise her salary to HK$6,692, meaning her hourly rate would not fall under HK$28 even after including lunch breaks and holidays.
