Incident log

Two incidents

  • INC-1: An employee was told she was entitled to 2021 parental-leave terms. The 2024 policy is more generous; she nearly agreed a shorter leave plan.
  • INC-2: A warehouse operative asked about redundancies at the Leeds depot. The assistant summarised a confidential consultation plan that had not been announced.
