Open Shift
Definition, rules and examples

Every hourly business deals with open shifts. Someone requests a week off, a new hire quits, or a busy weekend needs an extra person. How quickly and fairly those shifts are filled affects service, labor cost, employee satisfaction, and in some places, compliance with scheduling laws. A clear process turns open shifts from a last-minute scramble into a routine part of scheduling.

How open shifts work

A manager identifies a gap in coverage and creates a shift with a date, time, location, and role. The shift then needs to be filled, either by assigning it directly, offering it to a group of qualified employees, or arranging a swap between employees. Once filled, the shift becomes part of the employee's schedule like any other.

Example: weighing overtime when filling a shift

A retail store has an open 6-hour Saturday shift. Two qualified employees are interested:

Assigning the shift to Employee B saves $34.00 and gives hours to a part-timer who wants them. Under the Department of Labor's Fact Sheet #23, non-exempt employees must receive at least 1.5 times their regular rate for hours over 40 in a workweek, so the overtime in Employee A's column is a legal requirement, not a policy choice. You can model this with the overtime calculator.

Rules that can affect open shifts

There is no federal law about open shifts as such, but several rules shape how they are filled:

• Overtime. As above, hours over 40 in the workweek are paid at time and a half for non-exempt employees.
• Hours worked. The Department of Labor's hours worked fact sheet says work that is suffered or permitted must be paid, so any time an employee spends covering a shift counts, even if the assignment was informal.
• Predictive scheduling laws. Oregon's Bureau of Labor and Industries says that under the state's predictive scheduling law, covered employers that add a work or on-call shift without 14 days' notice generally owe one extra hour of pay at the regular rate, unless the change was requested by the employee or another exception applies. The law also requires a written explanation of the voluntary standby list for new employees. Seattle's Secure Scheduling Ordinance requires covered employers to post schedules 14 days in advance and allows employees to decline hours not on the originally posted schedule.
• Rest between shifts. Both Oregon and Seattle require time-and-a-half pay, for covered employers, for hours worked within 10 hours after the end of a prior shift (with exceptions). Filling a morning open shift with someone who closed the night before can trigger it.

See predictive scheduling for more on these laws.

Best practices for filling open shifts

• Write down the process. Decide the order in which employees are offered shifts and apply it consistently.
• Check qualifications first. Make sure only trained or certified employees are assigned to shifts that require it.
• Look at weekly hours before assigning. Avoid creating overtime when another qualified employee is available at straight time.
• Prioritize employees who want more hours. Offering shifts to part-timers seeking hours can improve retention.
• Use swaps with approval. When an employee cannot work a shift, let them propose a qualified replacement for the manager to approve.
• Plan ahead for predictable gaps. Approved time off and seasonal peaks can be scheduled weeks in advance, which also helps under advance-notice laws.
• Track patterns. If the same shifts are open every week, adjust your base schedule or hiring plan.

Common mistakes

• Giving open shifts to the same few employees, which creates overtime and perceptions of favoritism.
• Filling shifts by group text with no record of who was offered what and when.
• Ignoring rest-between-shifts rules in cities or states that have them.
• Adding shifts late without checking predictability pay obligations where they apply.
• Assigning untrained employees just to fill a gap.

A simple open-shift policy template

A short written policy helps managers and employees know what to expect. It might cover:

1. How open shifts are announced: for example, posted in the scheduling system as soon as they are known.
2. Who is eligible: employees trained for the role and location.
3. Order of priority: for example, part-time employees seeking more hours first, then employees who would stay at or under 40 hours, then others.
4. Response time: how long employees have to express interest before the manager assigns the shift.
5. Final approval: the manager confirms the assignment and the schedule is updated.
6. Records: who was offered the shift, who accepted, and when.

Keeping records of how shifts were offered also helps answer questions about fairness and, where local laws apply, shows whether a change was employee-requested or employer-initiated. Review the records every few months to see whether open shifts are being shared fairly across the team.

How EZTime helps

EZTime helps managers fill coverage gaps through scheduling tools rather than an open-shift marketplace. AI shift scheduling suggests coverage based on your rules, shift templates make recurring schedules quick to build, and shift swaps with manager approval let employees trade shifts while managers keep control. PTO and absence management shows approved time off in advance, so gaps are visible early, and overtime and break alerts help you avoid surprise overtime. Employees clock in with a GPS mobile time clock with geofencing, NFC tags, a tablet kiosk, or biometric clocks. Payroll-ready Excel and PDF exports work with any payroll software; EZTime does not run payroll. Plans start at $2 per employee per month with a 14-day trial. See scheduling software and pricing.
