Comparison

When I Work for staffing agencies? Here’s the honest split.

People search “When I Work for staffing agencies” when they need to fill open shifts fast. When I Work is strong employer scheduling for a workforce you already employ on one site or brand. FillYourShift is staffing agency software that fills shifts from your existing roster — bulk email and opt-in SMS invites, magic-link apply, approve/reject, timed-shift reminders, and a reliability score. Same word “shifts.” Different job.

FAQ

Can a staffing agency use When I Work?

Some try. If your pain is posting open shifts to your own temp roster with bulk invites and show-up history, FillYourShift is built for that job.

Does FillYourShift replace When I Work?

Not as a general employer scheduler. It replaces group-chat and spreadsheet shift filling for agencies.

Marketplace or roster?

Roster only. Your people. Not a labor marketplace.
