To help out some of the less informed posters that are quoting class action, be aware that type of action is illegal and I really wouldn't go there.
UAE LABOR LAW
The Law covers all aspects of the employer-employee relationship (Chapter 12), including matters related to employment contracts, restrictions on the employment of juveniles and women, maintenance of records and files, wages, working hours, leave, safety and protection of employees, medical and social care, codes of discipline, termination of employment contracts, end of service benefits, compensation for occupational diseases, labour inspections, penalties and employment related accidents, injuries and death.
The UAE does not allow the formation of trade unions.
It makes an interesting read and offers protection in both directions to some degree.
