Do enterprise apprentices need to sign labor contract law with enterprises?

A few enterprises unilaterally draw up a factory entry agreement for new employees, treating each other as "apprentices", not only forcibly collecting deposits and training fees, but also not signing labor contracts with employees. In this regard, it should be accurately said that "apprentice" is just a statement of enterprises and has no legal basis. If the enterprise has these behaviors, it should pay double wages to these "apprentices" during the period when they have not concluded a written labor contract according to law. Please note the following points:

First, the recruited apprentice must be 16 years old, and the probation period is mandatory.

(1) If the term of the labor contract is more than 3 months (inclusive) but less than L years (inclusive), the probation period shall not exceed L months;

(2) If the term of the labor contract is more than 1 year but less than 3 years (inclusive), the probation period shall not exceed 2 months;

(3) The probation period of fixed-term and non-fixed-term labor contracts of more than 3 years (including 3 years) shall not exceed 6 months;

2. The Labor Contract Law stipulates that the wages of workers during the probation period shall not be lower than 80% of the minimum wage of the same position in the unit or the wages agreed in the labor contract (the wages after the expiration of the probation period agreed in the labor contract concluded between the worker and the employer), and shall not be lower than the minimum wage standard in the place where the employer is located.

3. When employing workers, the employer shall not detain the workers' resident identity cards and other documents, and shall not require the workers to provide guarantees or collect property from them in other names. So you can't accept a deposit.
