Companies most often use the trial period to assess whether a given candidate will be appropriate for a specific position. Over this period an employee is closely observed, and his/her level of substantive knowledge, motivation, results and potential are assessed.
However, it's not enough for many employers – especially from the financial and IT sectors. The employment history of people employed on positions such as administrator of systems/database, Developer, Director of the Branch of the Bank or other role having access to sensitive assets of the company should be checked in the database of the Penal Register and the Debtors Register. The trial period itself may not be enough to verify whether an employee really is whom he/she claims to be. Your company may discover the truth too late.
