Legal analysis: whether the probation period of six months is illegal or not needs to be judged accurately in combination with the term of the labor contract. If a fixed term of more than three years is agreed upon, if there is no fixed term, a probation period of six months may be agreed upon.

Legal basis: Article 19 of the People's Republic of China (PRC) Labor Contract Law stipulates that if the term of the labor contract is more than three months but less than one year, the probation period shall not exceed one month; If the contract term is more than one year but less than three years, the probation period shall not exceed two months and six months.
