Although permanently preoccupied by compliance and risk preventing, most HR departments fail to integrate compliance in their day to day activities.
Working under tough deadlines, many HR functions are typically understaffed and overworked. This leads to involuntary errors some of them even redundant (e.g.: errors in formulas used to prepare the import files, monthly particularities that are overlooked etc.).
While some level of errors and omissions are to be expected in any major HR process most can be prevented.
