Sorry, I was wrong on this detail information.

I said:  上面的是工作三年以上的员工， 不到三年的是 70 % base salary。 

Actually the difference is between exempt employees and non-exempt employees:

 

 

Company-Paid Basic Short Term Disability

 

Short Term Disability (STD) benefits provide a percentage of your earnings in disability income, for approved STD claims, as shown in the chart below.

For non-exempt employees, the longer you are employed with the Company, or one of its subsidiaries, the higher percentage of your earnings you will receive for STD, up to 26 weeks including the one week waiting period during which you will use PLB/PTO.

Exempt employees receive 100% of pay while out on an approved STD claim, after a one week waiting period during which you will use Flexible Time Off (FTO).

Years of Service	Non-Exempt Employees STD Coverage Amount	Exempt Employees STD Coverage Amount
Fewer than 3 years	50% of eligible earnings	100% of eligible earnings
3 years to fewer than 8 years	60% of eligible earnings	100% of eligible earnings
8 years to fewer than 15 years	70% of eligible earnings	100% of eligible earnings
15 years or more	80% of eligible earnings	100% of eligible earnings
