Part-time employees (half-day, half-week, half-month) are those whose regular working hours (daily, weekly, monthly) is less then collectively agreed or customary hours for the observed local unit or occupational group.
Days worked - the total number of days worked by all employees under labour contract during the reference year. For a day worked is considered every day spent on work irrespective of the number of actual hours spent.
Days not worked but nevertheless paid by the employer - the number of days not worked due to annual holydays/vacation, absence due to sickness (if it is paid by the employer), public holydays and other paid but not work days.
Hour actually worked - the total number of hours worked by all employees during the year. Hours actually worked are defined as the sum of all periods spent on direct and ancillary activities to produce goods and services.
Total Labour Costs includes wages and salaries paid by the employer in cash or in kind, employers' actual and imputed social contribution, taxes regarded as labour costs, vocational training costs and other labour costs.
Gross annual wages and salaries are the remunerations paid regularly to the employees by the employers before the deduction of any tax and social security contributions payable by the employees and withheld by the employers.
Gross wages and salaries comprise of:
- basic wages and salaries for time worked or work done;
- payments for statutory, contractual or voluntary leave;
- payments for overtime;
- additional payments for shift work, extreme working conditions, length of service etc.;
- monthly, quarterly and annual bonuses.
Employers' statutory social-security contributions. These consist of payments made compulsory by law and payable by employers for the benefit of their employees to social-security institutions. They include contributions to insurance schemes for retirement pension, sickness, maternity and disability, to unemployment insurance schemes, to insurance schemes for occupational accidents and diseases etc.
Collectively agreed, contractual and voluntary social-security contributions payable by the employer - these are all contributions paid by the employer to social-security schemes which are supplementary to those which are compulsory by law. They include supplementary pension sickness and unemployment insurance schemes.
Employers' imputed social contributions these are payments made directly by employers to their employees or former employees without involving a social-security fund. Instead, the benefits are paid out of the own resources of the employers. Examples for such payments are: guaranteed remuneration in the event of sickness (for the first three days), payments to employees leaving the enterprise, payments made to employees on retirement etc.
Social expenses and benefits (payments in kind) - this variable refers to an estimate of the value of all goods and services made available to employees through the employer.
