  • Article 16.6 carries an express carve-out: it does not reach conditions «that require different treatment given their nature». Severance is counted over the whole relationship; other seniority-linked conditions may not be.
  • Where the contract is justified by a service contract, article 16.4 allows inactivity only as a waiting period between subcontracts, capped at three months absent a collective agreement.
