byalphaindia - NO union at EK! Those of us here knew that when we joined. It's the way the middle east is
Sadly the company employee manual is quite explicit about warnings and terminations - not fair but those of us here did sign the contracts. Maybe it could be fought in court but sometimes it's better to sign the resignation letter and go with your provident fund than get sacked and lose a large lump of it. (Not that they're worth much at the moment!!). It'll probably be easier to get another job following enforced resignation rather than a direct sacking - something else to think about.
It may not be right but that's the gamble you take working in the sandpit...
