Minimum Wage Proposal Causing Great Anxiety in Thailand News Posted August 1, 2011 Did I miss something? 6x4=24x300 = 7200 Or do your staff work 7 days per week and not 6 days as quoted above? and even if so how is going from 7500 to 9000 double the salary?? hmmm, why do you have 24 day? month has 4.3 weeks so its more like 26 days. My calculations are based on the fact that all my staff are on salary and have a paid day off, so in fact it is 9000 baht. Now if my new minimum is 9000 but now i am paying 30% more, that means i would need to pay 30% more on 9000 making it 11700. As i said its almost a double from 7500.
