Kuwait Court of Cassation principle number 4392

A worker’s basic wage. What is considered an addition to it and is treated in the same manner is what is paid to the worker regularly and continuously until it acquires a habitual character, with reliance upon it by the worker in organizing the worker’s livelihood. Excluded from this are benefits in kind provided on account of the work rather than as consideration for it. An example: the benefit of free medical treatment or an allowance for medical treatment expenses.
