Hello,

You can see https://www.odoo.com/apps/modules/10.0/hr_overtime_request/ and https://www.odoo.com/apps/modules/10.0/print_timesheet_regular_overtime/

Regards.

For that you have to customize ..

 hope this is required scenario:

If a company have total working hours =170 hrs/for a month

Then if a employee works total 180 hrs in a month that means 10 hr consider as overtime 

For that we need to customize in payroll module for automatic calculation of overtime
