How to calculate basic working hours?

Calculation method of standard working hours: standard working hours = normal working hours X( 1+ width ratio);

Width ratio = (standard working hours-measured working hours)/measured working hours * 100%= management width ratio+physiological width ratio+fatigue width ratio;

Normal working time is the sum of working time of manual operation unit (after speed evaluation)+automatic working time of machine (without speed evaluation);

The magnification is mainly the sum of the following aspects: 1. Physiological amplification is generally 2%~5%. 2. Fatigue tolerance is generally 5% ~ 20%; 3. The management magnification is generally 3% ~ 10%. 4. Special magnification The magnification used in the electronic manufacturing industry is generally 10%.

2 1.75 days is the monthly paid days stipulated by Ministry of Human Resources and Social Security. No matter whether your actual working days are more than 2 1.75 days (such as July and August) or less than 2 1.75 days (such as 10 month and Spring Festival month), the monthly paid days are 2 1. This 2 1.75-day period only has a unified formula for calculating overtime pay, which is not used to calculate monthly pay at ordinary times.

Under any of the following circumstances stipulated in Article 44 of the Labor Law, the employing unit shall pay the wages higher than the wages of the workers during their normal working hours according to the following standards: (1) If the workers are arranged to extend their working hours, they shall pay the wages not lower than 150% of the wages; (2) If workers are arranged to work on rest days but cannot be arranged for compensatory time off, they shall be paid a salary of not less than 200% of their wages; (3) If workers are arranged to work on legal holidays, they shall be paid no less than 300% of their wages.
