Mr. A worked for Company XYZ under 3 labor contracts: the first labor contract was for a term from 1 Jan 2001 to 31 Dec 2001. The second labor contract was for a term from 1 Jan 2002 to 31 Dec 2003. The third labor contract was for a term from 1 Jan 2004 to 31 Dec 2005. On 1 May 2005, as there was another company that offered A a higher remuneration, A unilaterally terminated the labor contract with Company XYZ after 60 days advance notice.
1. Please comment on the 3 labor contracts mentioned above.
2. Is it legal for A to unilaterally terminate his labor contract like that?
3. What would be A's rights and obligations when he terminated his labor contracts in such situation?
