# how to add noumber of holydays as worked days for employee has full attendance?

hi
I have a certain policy:
in the company there is holyday, Sunday for example
*** If the month is 30 days so there is 26 working days and 4 holidays
take an example for employee salary 600\$ for 30 days and 620\$ for the 31-month days
the policy says:

• The salary is divided for 30 days not for 26 days (600\$/30=20\$ per day)
• If this employee works all the 26 days with no absence, then I want to give him 600\$
• If this employee works 25 days (1 absence), then I discount 1 day and give him 580\$
• If this employee works 24 days (2 absence), then I want to discount 2 days absence and 2 days from holydays (600\$-40\$-40\$=520\$)
• If this employee works 23 days (3 absence), then I want to discount 3 days absence and 3 days from holydays (600\$-60\$-60\$=480\$)
• If this employee works 22 days (4 absence and more), then I want to discount absence days and don’t give him holydays salary (600\$ - number of absences - all holydays occur in the month = total) or (number of worked days * salary per day = total)
*** In the 31-days month: If the employee works 22 days (5 absences and more), then I want to discount absence days and don’t give him holydays salary (620\$ - number of absences - all holydays occur in the month = total) or (number of worked days * salary per day = total)
how to enter this policy in ERP?
thank you
