Air India Express sources today said that the airline does not recognise any workers' union amidst protests from employees who are opposing a new merit-based assessment system. This system, part of a broader performance appreciation policy, aims to streamline operations and effectively handle cancelled flights. However, it has sparked discontent among employees, particularly the cabin crew. The latest development comes after 86 flights were cancelled today due to a mass sick leave taken by cabin crew members, leaving hundreds of passengers stranded.
