Time and Attendance
Definition
Time and attendance is the process and system an employer uses to record when employees start and stop work, take breaks and are absent, and to turn those records into paid hours. For hourly employees it is the basis for payroll and overtime, and US law requires accurate records of hours worked.
Also called: Timekeeping, Time tracking, T&A, Time clock system
What a time and attendance system does
At its simplest, timekeeping is a time clock and a timesheet. In most organizations with hourly staff it has grown into a system that does five jobs:
- Capture time: clock-ins and clock-outs from a physical clock, a mobile app, a web portal or a phone line.
- Apply rules: rounding, meal break deductions, overtime, shift differentials and pay codes.
- Track absence: sick days, PTO, leave, tardies and no-shows.
- Compare against schedule: flag late arrivals, early clock-ins and missed punches against the shift schedule.
- Feed payroll: approved hours flow to payroll for each pay period.
The last step is where errors cost money. A rule configured wrongly, such as an automatic 30-minute meal deduction that runs even when no break was taken, repeats on every paycheck for every employee until someone notices.
What US law requires
Under the Fair Labor Standards Act, employers must keep accurate records of hours worked each workday and workweek for non-exempt employees. The federal record-keeping rules require payroll records to be kept for at least three years, and the time cards and other records used to compute wages for at least two years. States often add their own requirements.
Key points for timekeeping:
- All hours worked must be paid, including pre-shift work such as booting up computers or putting on required protective gear when it is integral to the job.
- Overtime is due at time and a half for hours over 40 in a workweek under federal law; some states, including California, also require daily overtime. See overtime for detail.
- Rounding to the nearest 5 minutes, tenth of an hour or quarter hour is allowed federally only if it is neutral over time, so it does not consistently favor the employer. Some states are stricter; California's Supreme Court ruled in 2021 that employers cannot round meal period punches.
- Meal and rest breaks are not required by federal law for adults, but many states require them, often with penalties for missed or late breaks.
Rules vary by state and country. A system configured for one state's rules can quietly break another state's.
Time clock options
- Physical clocks with badges or PINs: cheap and familiar, but prone to buddy punching.
- Biometric clocks (fingerprint, face): stop buddy punching, but carry legal obligations. Illinois's Biometric Information Privacy Act (BIPA) requires written notice, consent and a retention policy before collecting biometric data, and has produced large class actions. Texas and Washington have biometric laws too.
- Mobile apps with geofencing: good for field, multi-site and remote staff. Tell employees what location data is collected and when.
- Computer login or softphone status: common for contact center agents. Make sure the time recorded starts when work starts, which may be before the agent's phone is ready.
For high-volume operations, the best choice is usually the one that minimizes missed punches, because every missed punch creates a manual correction and a chance for a payroll error.
Time and attendance in high-volume workforces
In a 600-person distribution center or a 400-seat contact center, attendance data is operational data. Supervisors need to know by 7:15 am who is missing from the 7:00 am shift so they can call in replacements or move people. That means real-time dashboards, automated alerts for no-shows and an easy way for employees to report an absence before a shift.
The same data drives attendance policy. Absences, tardies and points under an attendance point system should be calculated from the timekeeping record, not from a separate spreadsheet, with protected leave coded so it never counts. New hires are a useful segment to watch: early attendance problems in the first two weeks often predict who will leave in the first 90 days. Some employers track new-hire attendance from the first day of training so that recruiting and operations see the same picture.
Common mistakes
- Auto-deducting meal breaks without a way for employees to record a missed break.
- Rounding that always rounds clock-ins up and clock-outs down.
- Supervisors editing time records without an audit trail or employee confirmation.
- Not paying for short pre-shift tasks such as security screening when they are required and integral to the job (rules here vary and have been heavily litigated).
- Treating the system as a payroll tool only, so attendance trends are never reviewed.
Frequently asked questions
What is the difference between time and attendance and timekeeping?
Timekeeping usually means recording hours worked. Time and attendance is broader: it covers timekeeping plus absence tracking, schedule comparison, leave balances and attendance policy. In practice the terms are often used interchangeably.
Do salaried employees need to track time?
Exempt employees are not subject to the FLSA's hours-worked record requirements in the same way, but many employers still track their PTO and leave. Non-exempt salaried employees must have their hours recorded because they are entitled to overtime.
Is time clock rounding legal?
Under federal rules, rounding to the nearest 5, 6 or 15 minutes is allowed if it is neutral over time and does not result in employees being undercompensated. Some states restrict it, and California does not allow rounding of meal period punches.
How long must employers keep time records?
Federal rules require payroll records for at least three years and time cards used to compute wages for at least two years. Several states require longer retention, so many employers keep time records for four to six years.
What is time tracking for employees used for besides payroll?
Attendance management, overtime control, labor cost reporting, schedule adherence, compliance with break rules, and evidence in wage disputes. In high-volume operations it also feeds real-time staffing decisions on each shift.
