In Russia, Kazakhstan and Belarus
Russia
When paying wages, the employer must tell you in writing what they consist of (Art. 136 of the Labour Code). The payslip can be given on paper or sent electronically; the company approves its own form.
Kazakhstan
The employer must give the employee a payslip (расчётный лист) showing the components of the salary, deductions and the amount to be paid.
Belarus
Each time wages are paid, the employer tells the employee their components and the amounts withheld — usually in a payslip (расчётный листок).
