Airline workers strike Oman Air
The leader of the airport employees union, Saleh Bin Mohammad Abdullah Al Zedjali, said that workers “had been demanding training and promotions for Omani staff for some time but, despite promises, the company had not implemented any of the demands”. He also said that employees were being made to work more than eight hours by the airline without being paid overtime wages.
Other grievances are over long hours and late nights, which even women are forced to work. The union alleges that the company deducts pay even when employees submitted legitimate medical bills and that it had been withholding increments.
