未成年工是否可以加班？

Temporary or periodical exceptions apply in cases where work has to be carried out outside normal hours to address the temporary necessities of an undertaking, and where the exact period at which such work has to be carried out cannot be foreseen. “Overtime” covers only additional hours that are worked in cases of temporary exceptions, which include – 

(a) situations of accident, actual or threatened, force majeure, or urgent work to machinery or plant, but only so far as may be necessary to avoid serious interference with the ordinary working of the establishment; 

(b) work that has to be carried out to prevent the loss of perishable goods or avoid endangering the technical results of the work; 

(c) special work such as stocktaking and the preparation of balance sheets, settlement days, liquidations, and the balancing and closing of accounts; 

(d) situations of abnormal pressure of work due to special circumstances, in so far as the employer cannot ordinarily be expected to resort to other measures.

国家没有明确的规定，某些省的劳动保护条例或者未成年人保护条例里面有规定未成年工不允许加班。

用人单位使用已满16周岁不满18周岁未成年工必须按照国家人力资源和社会保障部《未成年工特殊保护规定》第六条规定对未成年工进行健康检查并到当地人力资源部门办理未成年工备案，不得安排未成年工从事国家人力资源和社会保障部《未成年工特殊保护规定》第三条规定范围的劳动。《中华人民共和国劳动法》第四十一条规定，用人单位由于生产经营需要，经与工会和劳动者协商后可以延长工作时间，一般每日不超过1小时；因特殊原因需要延长工作时间的，在保障劳动者身体健康的条件下延长工作时间每日不得超过三小时，但是每月不得超过三十六小时。
