Create a leave policy. It's active right away and takes effect today. Describe each leave type it earns in one of three lists: accruedLeaveTypes for leave earned as workers work, frontLoadedLeaveTypes for paid leave granted in a lump each period, and unpaidFrontLoadedLeaveTypes for unpaid leave granted the same way. Leave types are referenced by name, so they must already exist. See List leave types and Create a leave type.

The policy needs at least one leave type, and each leave type can appear only once. If a leave type has no pay code yet, one is created. See the Guide to the Leave Accrual API for how award rules and tenure tiers work.
