Potential Employee : binded or employee patience in work??

there are many indonesian company conduct a binding contract for their potential employees, a binding contract usually has a term of agreement which one employee should work at the company for at least 1-2 years of service, and a long that year of service the word “ resign” or “i quit” or “i have a better over” will cost them a large amount of money, they call it Penalty Payment ( penalty fee around Rp 10.000.000 – Rp 75.000.000,- or around 1.000 USD – 7.500 USD ).

back to one notable finance company in indonesia which has highly number of employees turn over did the same thing, they bind their employees with the contract. A binding contract usually offer to the employees at this situation;
1.a new employees ( from a recruitment process ), usually the contract bind the employees until 2 years of service
2.An Employees who got promoted, usually the contract bind the employees until 3 years of service
3.An employees who has just finished their training ( a common training such a new standard operation procedure knowledge, etc )

it seems that the company use every reason and every term to bind their employee, it is quite understandable regading the company turn over which the level of employees out is get a bigger number??
