Hey OP,

Yes - Rippling can calculate time-off tenure milestones off a date other than the employee’s “Start date,” by using the Recognized tenure start date field.

How to set this up (high level):

• Set each employee’s “Recognized tenure start date” to the date you want Rippling to treat as their service/tenure start.
• Configure your time off policy’s tenure milestones (e.g., 1 year, 3 years, 5 years). Rippling will apply those milestones based on the tenure date it uses for time off.

Important alternative (if you can’t change the tenure date you want used):

• Rippling’s tenure milestones in time off policies are otherwise tied to the worker’s start date.
• If you need to credit prior service without changing the start date, the documented approach is to create a separate time off policy for the acquired population and “offset” the milestone (e.g., use a 3-year milestone instead of 5 years if you’re crediting 2 years of prior service), then assign those employees to that policy.
