Typically the employee's father (or some similarly close relative) will sign a legal agreement with the employer promising to pay back the employee's wages if the employee disappears. (Legally I believe this is similar to a guarantor for a bank loan.) Though this probably won't stand up in court, most employees wouldn't risk putting their own father through the trouble of finding out.
