Retiring peoples for organization restructuring

Last week, one of my collegues is resigned from our company. Actually restructuring might be very important for surviving the company, but firing people is not proper action from company. This is the reason why company hire by contract. Contract is really simple way to maintain company.

In Korea, there are two types of employees: one is regular, and second is contract. The regular employee is protected people by company, but the contract is not.

Actually this is unfair rule on earth. I am regular employee in current company, but I feed some kind of sympaty for them.
