Given that UK salaries in general are rising at around 3.1% a year 11% over 3 years isn't exactly generous...................
The Hays Salary study shows
"For the third year in a row, the Hays Asia Salary Guide has reported prevalence in salary stagnation in Hong Kong, culminating in one in ten (11 per cent) employees experiencing no increase in their salaries over the last year. However, this rise is fractional and still below the Asia average of 15 per cent.
In addition, signalling salary inertia in Hong Kong was the rise in employers reporting conservative increases of up to three per cent. In 2018, 27 per cent of employers had intended salary raises by this marginal amount, but this figure leaps to 35 per cent in 2019."
which sounds quite similar to the UK
