Sompo Japan Insurance Inc. will use former employees to cover the jobs of incumbent employees on child care leave from July, company officials said Thursday.

The nonlife insurance company has devised the childcare system following a new law that took effect in Japan last month to help support employees' child care.

Sompo Japan will register those who quit the company for childbirth or other reasons and are willing to work at the company again, so that they can fill jobs vacated temporarily by employees taking one-year child-care leave.

When those on child care leave return to the workplace, the makeshift employees may be allowed to continue working depending on their willingness and workplace requests, the officials said.

Sompo Japan expects to register about 3,000 former employees before the system is launched. The company had 14,700 employees at the end of March. In fiscal 2004, 98 employees took child care leave.
