1. Holiday pay must include all ordinary salary items
        The Labour Chamber of the Supreme Court revised its case law and stated that   collective bargaining agreements must always respect EU directives and their   interpretation by the Court of Justice of the European Union. In this case, the   Supreme Court held that all workers’ ordinary salary items must be taken into   account to calculate holiday pay.

2. Workers need not notify the company in advance to enjoy the flexible   working hours established in a collective bargaining agreement 
        The Supreme Court held that workers do not have to notify the company in   advance to enjoy the flexible working hours established in the collective   bargaining agreement, provided that the new working hours are within the working   day set by the collective bargaining agreement. The Supreme Court stated that   the company’s argument that workers were deprived of this right because of the   cost of maintaining a monitoring system was groundless.

3. Concept and application of the principle under which there must be unity   between back-to-back temporary employment contracts
        In this case, a worker was dismissed after working under approximately 20   temporary employment contracts during seven years with a seven-month break   between the penultimate and final contract. The Labour Chamber of the Supreme   Court dismissed the cassation appeal and confirmed the decision of the High   Court of Justice of Castile and León, which had held that the principle under   which there must be unity between back-to-back temporary contracts (unidad   esencial del vínculo) did not apply because the continuity of the   contractual relationship had been broken.

4. Contractual subrogation. The liability in article 44 of the Statute of   Workers does not apply in cases of contractual succession derived from the collective bargaining agreement
        The Supreme Court held that, in cases of contract succession imposed by the   collective bargaining agreement, the company succession regulation set out in   article 44 of the Statute of Workers does not apply. The subrogation is instead   regulated by the collective bargaining agreement itself.

5. Back-pay extends to the notification of the court ruling clarifying the   decision
        The Supreme Court confirmed that back-pay (salarios de tramitación)   extends to the notification of the court ruling clarifying the decision,   provided that clarification has not been sought to delay the proceedings.

6. The employment conditions in an extra-statutory agreement need not be   maintained nor are workers entitled to the conditions that are more favourable   after its expiry
        The Supreme Court held that a company is entitled to modify the contents of   an extra-statutory agreement following its expiry, without that circumstance   being considered a substantial modification of working conditions. This is due   to the fact that the agreement is not a collective bargaining agreement and thus   its effects do not continue to apply after it expires (i.e. it does not have ultraactividad).

7. A company is not entitled to file a claim requesting that a collective   redundancy agreed with the works council be declared lawful
        The Supreme Court held that, once an agreement with the company’s works   council has been reached which concludes a collective dismissal process, the   company is not entitled to file a claim requesting that the redundancy decision   be declared lawful.

8. Reducing incentives in response to workers’ exercise of their statutory   right to paid leave is unlawful
        The National Court declared that considering workers’ legal and statutory   paid leave as an absence from work for the purpose of a voluntary bonus plan is   unlawful. This practice is also indirectly discriminatory towards women and is   generally an abuse of workers’ rights.
