Backpay computation

Hi,

Just wanted to know kung paano na c-compute ang back pag nag resign sa company.

Here are the details of my employment:

1. I resigned last August 29, 2017 (immediate resignation) - sent an email to the HR manager and my manager for my intent because of health issues. Previous weeks before I filed I have been sick most of the time and was rushed to the E.R several times
2. They did not accept my resignation and they were asking for a medical certificate from my doctor stating that I am not fit to work but prior to my resignation I have always provided medical certificate for my absences and it reached to the point that I am so stressed already and cannot perform my duties at work because of my sickness.
3. Had my clearance processed last October 13th and was told that my back will be released after a month.
4. Few days ago they have sent me a draft of my last pay computation but I was amazed that they included in their computation September 1 - 19 but I am no longer with the company. As I have stated above my effective resignation date was August 29.
5. They have deducted so much in my salary to the point that my final pay is less than my tax refund after they have computed it.

e.g Tax Refund - 15,000
13th month - 5,000
Leave conversion - 4,000
Salary- 4,000



Final Pay - 13,000

no back pay for resigned employees

computation for final pay

salary = unpaid days work x rate per day
leave conversion = rate per day x leave credit remaining
13th month = total basic received for the months that you had worked divided by 12
tax refund - if you did not reached your personal expemtion, all tax deducted to you. if yo received your exemption, the computed excess will be returned to you.

can you share with me the specific article in labor for this so I can review it as well and send it to our HR manager and payroll team? thanks in advance..
