Want to know how this company's salary is calculated!
A into a piece and no minimum wage company
For example, if you work 8 hours a day and the standard quantity is 4500 pieces, you can get 1300 yuan if you can reach this quantity every day in 26 working days
Then because we do fast and slow, the company also launched an efficiency factor
According to your daily, hourly workload to assess your efficiency coefficient, normal is 1, do more is 1.2 times, do less is 0.8
So if you work 11 hours a day (Overtime)
How much is the efficiency coefficient of 6000 in 11 hours? Is the salary multiplied by that day?
What's the efficiency factor of 6000 in 8 hours?
If someone doesn't think it's possible that I didn't make it clear, you can ask me. Please be sure to help me figure it out


The coefficient is 0.8 for 11 hours and 1.2 for 8 hours
