#### Average paid employment to calculate the average monthly wages and salaries

**Definition:**

The average paid employment rate for the surveyed period (e.g. month, quarter, year), based on the employment rate in the books, excluding persons employed abroad and having converted part-time paid employees into full-time paid employees.

Census enumeration of part-time paid employees per full-time paid employees is obtained through multiplying the number of part-time paid employees by appropriate conversion factors which are the rates of the number of working hours of part-time paid employees to the number of working hours of full-time paid employees, that is to nominal working time. The average monthly employment rate is calculated as the arithmetic mean or using the simplified method, i.e. as the chronological mean or the two days state mean. The average monthly employment rate, calculated using the arithmetic mean method, is the quotient of sums of paid employment on individual working days in the given month and the number of calendar days in a month. Working days in a month include Sundays, holidays and bank holidays as may occur. The paid employment level on those days is assumed to be as on the previous day or on the following day, if the month starts with a bank holiday. When determining the paid employment level of the day, persons on unpaid leaves, parental leaves and persons receiving sickness benefits, maternity benefits, paternity benefits, parental benefits and care benefits are not taken into account. The average monthly paid employment calculated using the chronological mean method is half of the sum of: half of the paid employment level on the first day of the month, the paid employment level on 15th day of the month and half of the paid employment level on the last day of the month. The average paid employment computed using two days state mean method is counted as the half of the sum of paid employment state from the first and the last days of the month. Using the simplified method, persons on unpaid leaves, parental leaves and persons receiving sickness benefits, maternity benefits, parental benefits and care benefits more than 14 days are excluded from the level of paid employment. The simplified method to calculate the average monthly paid employment is used only with regard to work places with stable staff situation. In the case of work places operating for less than a month (newly established, starting their activity in a reporting month, seasonal) as well as work places with big staff fluctuation (mass lay-offs, intensity of unpaid vacations, etc.) the arithmetic mean method is used. Average paid employment: in a quarter, from the beginning of the year till the end of a reporting period, in a year, is the quotient of the sum of the average number of employees in particular months of: a quarter, reporting period, year, and the number of months in a given period respectively. Where an enterprise did not function for an entire: quarter, reporting period, year, the average paid employment is the quotient of the average number of employees from months during which the work was really carried out and full number of months in: a quarter, reporting period, year respectively.
