1. INFRINGEMENT OF TRADE UNION FREEDOMS  DURING NEGOTIATIONS ON INTERNAL FLEXIBILITY MEASURES
        Judgment of the Supreme Court dated 22  July 2015
        The Supreme Court (“SC”) ruled on an appeal lodged by two banks against a judgment of  the Labour Chamber of the National Court, dated 14 November 2013, which held  that several internal flexibility measures implemented by the banks were void. 
        The background to the case brought before the SC is as  follows: (i) two banks informed their employees’ trade union representatives  that they wanted to start formal negotiations on the introduction of several  internal flexibility measures that would entail substantial changes to working  conditions, opting out of applying collective bargaining agreements, suspending  employment contracts and reducing working hours; (ii) after four meetings, the  formal negotiations ended without an agreement between the parties (the banks  as employers, and the trade union representatives as the employees’  representatives); (iii) the banks informed the labour authorities and their  employees of their final decision; (iv) the trade unions simultaneously initiated  mediation proceedings before the public mediation and arbitration body (“SIMA”); (v) the banks decided to  initiate informal negotiations with the trade unions representing the majority  of their employees affected by the measures and reached an agreement with them;  (vi) in the context of the SIMA proceedings, the banks put forward a new  proposal that was accepted by the trade unions representing the majority of employees,  but rejected by the other trade unions; (vii) the trade unions representing the  minority of employees brought a collective dispute claim against the parties  who reached the agreement before the SIMA, seeking to have it declared void on  the grounds that the banks and the majority trade unions had infringed trade  union freedoms protected by the Constitution.
        The first instance ruling held that the mediation  before the SIMA was a continuation of the formal negotiations initiated by the  parties to implement the internal flexibility measures. As representatives of the  minority trade unions were deliberately excluded from the negotiations between  the parties that reached the agreement, the first instance ruling held that trade  union freedoms were breached and, consequently, declared the internal  flexibility measures implemented according to the agreement void.
        The SC held that the first instance court’s reasoning  was flawed; however it also considered that the internal flexibility measures  should be declared void.
        Specifically, the SC held that the mediation  proceedings between the banks and the trade union representatives should not have  been considered an extension of the formal negotiations that must be held by  law to implement internal flexibility measures. The SC based its reasoning on  the following main legal arguments: (i) when the mediation proceedings began,  the formal negotiations had ended and the companies had already informed the  affected employees of their decision; (ii) the parties could not evidence that  an agreement had been reached to extend the formal negotiations; and (iii) the  possibility of reaching an agreement before the SIMA with the same legal  effects as an agreement reached in formal negotiations does not mean that there  was an implicit agreement between the parties to extend the formal negotiations  once ended.
        The SC found that the trade unions initiated the  mediation proceedings in compliance with articles 63 and 153.1 of the Labour  Procedure Law, which set forth that conciliation or mediation proceedings must be  held before filing a collective dispute claim.
        Having said this, the SC acknowledged that the banks’ decision  to exclude some trade unions from the negotiations was a breach of trade union  freedoms, as it was evidenced that the banks had deliberately decided only to negotiate  collective measures with the trade unions representing the majority of the  affected employees. 
        In conclusion, it is contrary to the trade union  freedoms guaranteed in articles 28 and 37 of the Constitution to exclude any  trade union from the formal or informal negotiation of collective employment  measures, even if the excluded trade unions adopt a far from constructive  approach to the negotiations, they represent a minority of the affected  employees, or even because of their limited involvement in the negotiations or  because they initiate legal proceedings against the employers.

        2. OPT-OUT AGREEMENTS DO NOT HAVE  RETROACTIVE EFFECT
        Judgment of the Supreme Court dated 7  July 2015
        The Supreme Court (“SC”) analysed the applicability of opt-out agreements (acuerdos de descuelgue) overriding the  terms of collective bargaining agreements (“CBA”). In particular, the decision examined whether the former  agreements can apply retroactively.
        In contrast with the arguments put forward by the  appellants, the SC confirmed that the freedom to lay down the term of  agreements, established in article 86.1 of the Statute of Workers (“SW”), refers only to CBAs and not to  opt-out agreements overriding stipulations of CBAs.
        In addition, the SC stated that article 82.3 of the  SW, which regulates the possibility of overriding stipulations in CBAs, does  not allow the parties to an opt-out agreement to set a term different than that  established in the CBA. The SC concluded that, although article 82.3 of the SW  does not expressly limit the retroactive effect of opt-out agreements, this can  be inferred from the SW itself. The SW states that “CBAs regulated by [the SW] are binding on all employers and employees  under its scope of application during their entire term.” Consequently,since the CBA must be applied in the  absence of an agreement confirming that it is no longer applicable, opt-out  agreements cannot have retroactive effect. In other words, opt-out agreements’  overriding stipulations in CBAs can only apply from the moment they are agreed  onwards.

        3. A FINAL FIRST INSTANCE JUDGMENT IN COLLECTIVE PROCEEDINGS CAN BE CITED  IN AN APPEAL TO THE SUPREME COURT TO UNIFY LEGAL DOCTRINE
        Judgment of the Supreme Court dated 16  June 2015
        The Labour Chamber of the Supreme Court (“SC”) has changed its doctrine whereby a  first instance judgment rendered in collective proceedings could not be used,  as a contrasting ruling, when appealing a decision to the SC. 
        The SC changed its doctrine as a result of the amendment  of the Spanish Labour Court Regulation (“LRJS”  for its Spanish acronym). According to article 160.5 of the LRJS, final  judgments rendered in collective proceedings have res judicata effect over ongoing or future individual proceedings  when they relate to a similar matter between the same parties. Particularly,  article 160.5 of the LRJS states that this res  judicata effect also applies to appeals to the SC, even if the final  judgment was not put forward by any of the parties as a contrasting ruling.
        The SC concluded that, according to the new wording of  article 160.5 of the LRJS, its previous doctrine needed to change. The SC stated  that a final first instance judgment rendered in collective proceedings can be  put forward when appealing to the SC because, otherwise, the fundamental right  to proper legal protection generally preserved by the res judicata effect would be lost. 
        In the case in question, the appellants considered that  the appealed decision contained an interpretation of a provision of their  company’s collective agreement that differed from that in another prior first  instance decision on the same matter in collective proceedings that became  final before the appealed decision was settled. The SC gave leave for the  appeal to proceed and then revoked the appealed judgment as it was contrary to res judicata.

        4. REDUCTION OF VARIABLE REMUNERATION DUE TO  COMPULSORY MATERNITY LEAVE
        Judgment of the Supreme Court dated 27  May 2015
        The Supreme Court (“SC”) analysed the legality of a company policy which reduced the  variable remuneration by the six weeks after childbirth that women on maternity  leave are entitled to.
        The variable remuneration policy required employees to  be present in the workplace to accrue the remuneration. Therefore, an  authorised absence of more than 30 days in a year entailed a reduction in  variable remuneration. The company’s policy stated that maternity leave was an  authorised absence that justified this reduction.
        The SC’s decision is based on its previous rulings as  well as those of the Constitutional Court. “Women’s  biological protection must be compatible with their career rights and any harm  to their career rights as a result of pregnancy or maternity leave is sexual  discrimination”. The SC rejected the company’s arguments regarding  managerial and organisational power and lack of discrimination as the policy  applied to both women and men. The company’s policy infringed the law as  clearly only women were eligible for those six weeks, and consequently the only  ones affected by this provision.
        Given the above, the SC held the company’s policy to  be discriminatory and obliged the company to repay any remuneration deducted  under the policy.

        5. SUBSTANTIAL CHANGE TO MORE FAVOURABLE CONDITIONS
        Judgment of the  National Court dated 27 July 2015
        This judgment  analysed a company’s decision to change employees’ working hours with a view to  determining whether or not the decision constituted a substantial change in  working conditions and, consequently, to confirm whether or not the changes  complied with article 41 of the Statute of Workers.
        In particular,  the case involved the company’s unilateral decision to eliminate compressed  working hours during the summer and on Fridays that employees had enjoyed for  ten years, as well as flexible working hours implemented in 2012. Despite the  company’s efforts to demonstrate that the flexible working hours programme was  merely a pilot and that, consequently, the company had merely tolerated the  situation, the National Court considered that it had been implemented much  longer than envisaged and that, as a result, it had become a real working  condition.
        Therefore, the  National Court concluded that a substantial change to working conditions had  been implemented, since the company’s decision significantly changed previously  established working conditions to the detriment of the employees. The National  Court declared the decision null since the company had not previously  negotiated with the employee representatives.
