A 'variable hour employee' is one whose work schedule fluctuates such that it's not clear at hire whether they will average 30+ hours per week. Florida hospitality, retail, and healthcare businesses commonly have variable-hour workers. The ACA provides a structured look-back method to determine when these employees qualify as full-time for health insurance offer purposes — different rules apply to ongoing variable-hour employees versus new hires whose status is uncertain at start.
An employee is variable hour at hire if it cannot be reasonably determined that the employee will average 30+ hours/week. Factors:
An employee who is hired at a fixed 40 hours/week is NOT variable hour and qualifies for coverage immediately upon completion of any waiting period (max 90 days under ACA).
For employees already in the workforce, apply the standard measurement period:
For new variable-hour hires, apply an initial measurement period:
Server hired June 1, 2026 with variable schedule. Restaurant uses 12-month initial measurement.
The stability period locks the coverage offer. If the variable-hour employee's hours fall below 30/week during stability, the employer MUST continue offering coverage. The stability period was the trade-off for the look-back's predictability.
If a variable-hour employee leaves and returns, ACA rules treat them as a continuing employee if the break is less than 13 weeks (26 weeks for educational institutions). Longer breaks reset the new-hire clock and a new initial measurement period applies.
Strictly, the §4980H rules apply only to ALEs (50+ FTE). Smaller employers have no mandate, but borrowing the measurement framework provides clarity for offering benefits to part-time staff and creates an audit trail if you ever cross the threshold.
Yes — even ALEs only have to offer to employees averaging 30+ hours. Smaller employers have full discretion. You can require any reasonable hours threshold (35, 40 hrs) as plan eligibility, but ACA mandate compliance requires offering at 30+.
Hours of service include all hours for which the employee is paid OR entitled to pay (regular work, vacation, holiday, illness, jury duty, military leave, FMLA, etc.). Unpaid leave generally doesn't count. Salaried employees use one of three IRS-defined methods (actual hours, 8-hour day equivalency, or 40-hour week equivalency).
