What if I work at multiple facilities/locations/clients in a week?

Last updated: August 2, 2026

Applies to: All workers who work at more than one client, facility, or location in the same week.

Summary: Enter your time against the assignment for the location or client where you actually worked. Getting the assignment right matters for correct billing, your taxes, and other compliance — and if you're a non-exempt employee, your overtime is calculated across all your hours for the week, no matter how many clients you split them across.

Always enter time to the correct assignment

Each client or location you work at is a separate assignment. When you enter time, pick the assignment that matches where you actually worked those hours. If you enter time under the wrong assignment, the wrong client may be billed or your time may not get approved.

If you don't see the correct assignment, contact your staffing partner or email support@ascen.com and ask them to add the correct assignment right away.

Why the correct assignment and work location matter

The assignment carries the work location, rates, and client for those hours — so it drives more than just billing:

  • Taxes. State (and local) income tax is generally based on where you physically perform the work. If you work in more than one state or locality in a week, your correct work location on each assignment is what makes your tax withholding right. See Working or living in more than one state: how state taxes work.

  • Compliance. Correct work location and assignment also keep workers' comp, pay rules, and other requirements tied to the right jurisdiction and client.

  • Getting paid correctly. Your hours flow to the right rates and the right client's approval when they're on the right assignment.

Overtime is across all your hours — not per client

If you're a non-exempt employee, overtime isn't counted separately for each client. It's based on your total hours in the workweek across every assignment — generally over 40 hours in the week (some states also have daily overtime). If your assignments have different pay rates, your overtime is figured on a blended (weighted-average) rate across those hours. This is normal and legally required — it doesn't mean you're underpaid.

Overtime rules apply to non-exempt W-2 employees; if you're a 1099 independent contractor they generally don't apply. For the full picture, see How overtime and double-time pay work.
