2. This Directive shall not affect the responsibility of Member States to ensure national security or their power to protect their essential security interests. In particular, it shall not apply to reports of breaches of the procurement rules involving defence or security aspects unless they are covered by the relevant acts of the Union.
3. This Directive shall not affect the application of Union or national law relating to any of the following:
(a) the protection of classified information;

4. This Directive shall not affect national rules on the exercise by workers of their rights to consult their representatives or trade unions, and on protection against any unjustified detrimental measure prompted by such consultations as well as on the autonomy of the social partners and their right to enter into collective agreements. This is without prejudice to the level of protection granted by this Directive.
