The cost of overtime for direct labor is usually assigned to overhead as well. The rationale is that typically no particular production run caused the overtime. Accordingly, overtime cost is common to all production runs and is therefore an indirect manufacturing cost. Note that only the overtime cost itself is treated this way, If workers are paid $16 per hour regular rate and a premium of $8 per overtime hour, then only the $8 overtime premium is assigned to overhead. The $16 regular rate is still regarded as a direct labor cost. In certain cases, however, overtime is associated with a particular production run, such as a special order taken when production is at 100 percent capacity. In these special cases, it is appropriate to treat overtime premiums as a direct labor cost.
