The General Data Protection Regulation 2018 gives you the right to ask your employer to give you all the information it holds on or about you, whether it’s in paper or electronic (ie computer-based) form. In order to get this information you need to make what’s called a Subject Access Request (SAR).
SARs are one way of acquiring useful information to support any dispute you may be having with your employer. They may also divulge information which can strengthen your hand if you are negotiating for a settlement.
For further details on when and how to make an SAR, have a look at our article on the subject.
