The rules that a swap can quietly break
Federal child labor rules set daily and weekly hour caps for 14 and 15 year olds, keep them out of work during school hours, and restrict how early and how late they can work, with a later evening limit during the summer. Workers who are 16 and 17 have no federal hour cap but many states impose their own limits, especially on school nights, and some require work permits or specific break rules. A swap that moves a 16 year old from a Saturday afternoon to a Tuesday close can be perfectly fine on total hours and still violate a state end-time rule.
The important thing for a manager to accept is that these rules vary by state and change over time, and that a swap is a schedule change like any other in the eyes of an enforcement agency. The state labor department website is the authority, not a memory of what the rule was three years ago. Build your process on the assumption that you will need to check, and make the check as automatic as possible. Related: Why should a manager keep a clear log of every shift change made?

Treat age as an eligibility attribute, not a note
Date of birth and school-enrollment status belong on the employee record as structured fields, so the swap system can compute eligibility rather than relying on the approving manager to remember that Maya is still 15. A pickup that would put a minor past the permitted end time or over the daily cap should be blocked at the request stage, with a message that explains why, so the employee does not waste effort and the manager does not have to be the bad guy.
The school calendar is the piece most teams miss. The daily cap for younger teens differs between school days and non-school days, and the evening limit shifts for summer. Keep the district calendar in the system, including early-release days and breaks, and let the rules engine read it. Without that, the rules are only as accurate as the last time someone updated them by hand. Related: How do you let staff swap shifts without ever losing coverage on the floor?
Hazardous tasks and role restrictions
Hours are only half of the picture. Federal hazardous occupation rules bar workers under 18 from certain tasks and equipment, including power-driven meat slicers, commercial bakery mixers, and balers or compactors, and younger teens face further limits on cooking and other kitchen duties. That means a swap from a front register shift to a deli or bakery shift can be a role problem for a minor even when the hours are identical.

Role eligibility therefore has to include age-gated tasks, not just certifications and training. If your roles are defined by station, add a minimum age to any station that involves restricted equipment, and let the eligibility check enforce it. Manager judgment alone is not enough, not because managers are careless but because a busy Friday is exactly when the detail gets forgotten.
Approval and documentation when a minor is involved
Any swap in which a minor is the receiving employee should require a manager's explicit approval rather than peer confirmation or an automatic rule, and the approval should be logged with the checks that were run. The direction matters: a minor giving a shift to an adult rarely raises an issue, while a minor picking up a shift is where hour, time-of-day, and task limits all come into play at once.

Keep records of hours actually worked, because enforcement looks at records and not intentions. Some employers also ask for a parent's acknowledgment of schedule changes for younger teens, which is not a legal requirement everywhere but is a practical way to avoid a phone call at 9 pm. ShiftTradr can block ineligible pickups and log the age checks, but the underlying rules still need someone who owns them for each state you operate in.
- Hour caps, permitted start and end times, and school-day rules apply to swaps exactly as they apply to the original schedule.
- Store date of birth and school status as structured fields and keep the school calendar in the system so eligibility is computed, not remembered.
- Restricted equipment makes some stations off limits for minors, so role eligibility must include a minimum age.
- Swaps where a minor picks up a shift should always require logged manager approval, with state rules layered on federal ones.
