If your request is related to the presence of a legal text in the labour law that regulates the way to calculate the delays at work, here is the following information:
There is no provision in the UAE labour law that regulates how delays are calculated.
You can check the internal regulations, which are supposed to exist in the workplace.
In addition, these regulations must be approved by the UAE Ministry of Human Resources and Emiratisation .
If there are no internal regulations about how delays are calculated, you can file a complaint to the Ministry of Human Resources and Emiratisation against the employer if he has deducted a sum of money from the salary that exceeds the actual number of minutes of delay.
