We would like to inform you that according to the Bahraini labor law in its articles stipulate on:
Article 99

· If the labour contract is terminated by the employer, an agreement may be made for increasing the notice period to more than thirty days.
· If the labour contract is terminated without abiding by the notice period, the party terminating the contract shall give the other party compensation for this period equivalent to the worker’s wage corresponding to all or part of said period as the case may be.
· If the labour contract is terminated by the employer, the notice period or the remaining part thereof shall be calculated as part of the worker’s service period. If the labour contract is terminated by the worker the contract shall be deemed terminated as of the date of abandonment of the work by the worker.
· If the employer sends the notice of termination of the contract, the worker may be absent from work for a whole working day or for eight working hours per week to search for another job, provided the absence is suitable with the work circumstances. The worker shall receive his wage for the working days or hours of absence.
· The provisions of this article shall not prejudice the right of any of the contracting parties to claim compensation for the termination of the contract if said compensation is due
Article 100

The employer may not recover the value of what has been lost or destroyed by deduction from the worker’s wage if this value exceeds two months’ wages.
