TOKYO — Honda workers are taking 14 additional days off during June through August because of production reductions caused by parts shortages, but will make up for those days later in the year.

Honda said today plant workers will take one extra day off in June, 10 more in July and three in August, and work those days in the latter half of the fiscal year to make up for the shortfall.

Separately, Honda has sent a message to workers and the union that employees may be asked to take additional days off in coming months if the parts shortages continue.

The March 11 earthquake and tsunami in Japan damaged hundreds of auto suppliers, forcing manufacturers, including Honda, to reduce production. Honda has said it doesn’t expect to return to normal levels of production until late this year.

Japanese automakers have already decided to work weekends and take Thursday and Friday off in July, August and September, peak months for electricity use in Japan, to avoid blackouts stemming from expected power shortages.

The government has asked major companies to reduce electricity use by 15 percent. The quake and tsunami hobbled the Fukushima Dai-ichi nuclear power plant, sending three reactors into meltdowns. The Hamaoka nuclear plant is also being shut down because of safety fears.
