Schooling is one major change from older contracts(13 years ago) as is the ERP, their is absolutely no reference to any cap of 15% as a maximum. However the company will not entertain that any money is owed to me or anyone else who signed prior to the change in 1995. Provided ofcourse your home currency has strengthened against the US DOLLAR.
The company simply responds by saying that "sorry, policy changed and therefore, it applies to everyone." Personally I am owed about 120,000 Dhs.
My contract also mentions schooling provided by company. No mention of any caps or future possible changes to the contract.
Medical and Clinics was another classic one. So the list goes on and on.
