4.2. In the event that the Contractor takes some forms of leaves (i.e. sick, vacation, personal leave), a consulting fee will be deducted by the amount of the following formula – (“a full monthly consulting fee” / “the total number of working days in that specific month”)*(number of day leaves in that specific month); for example, the total working day in a month is 20 and the Contractor takes 2 days leaves in that month, the deducted consulting fee in that month is equal to THB (XX,000/20)*2 = X,000 and the outstanding consulting fee is XX,000 – X,000 = XX,000 THB. In the case that the contractor is on sick leave, evidence must be presented in form of a medical certificate. Therefore, such consulting fees will not be deducted.
