A worker can have exactly one on-demand replacement per subperiod. This statement is:

• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

When a substitution is needed, it’s tied to a specific chunk of the payroll cycle called a subperiod. The on-demand replacement is meant to cover that exact segment, not multiple segments or multiple replacements at once. Limiting it to a single replacement per subperiod keeps payroll calculations clear and consistent: hours, rates, taxes, and any prorations are determined once for that subperiod and there’s no ambiguity about which substitute applies. If more than one replacement were allowed, it would create overlapping coverage and conflicting pay data, which the system avoids by design. So the statement is true because the setup enforces exactly one on-demand replacement per subperiod.
