Reducing the gratuity of an employee upon resignation due to late attendance

Greetings,

We hope you are well!

As we are processing the end of service gratuity for an employee (who resigned earlier), the daily attendance report during his employment (which all is available in official records) is showing that despite continuous official written notices (which are signed by him), he failed to follow the morning official starting working hours with continuous late attendance causing financial damage as work was delayed due to that.

We would like to know the rule which should be applied in order to deduct the late attendance hours during his employment out of his end of service gratuity (as per the biometric attendance report) due to the financial damage caused to the company.

Below are his employment details:

- Contract type: unlimited

- Start date: 13 July 2014

- Last day of service: 10 May 2021

- Notice period completed: 60 days approximately

- Reason for leaving the job: resignation from his position

- Basic salary: 4000 AED
