Understanding Wage Deductions and Bank Loans
The payment of wages is very clear. You cannot make any deduction from the wages of the employee other than those specified in Section 7 of the Act.
With reference to a bank loan, deductions can be made, and money can be paid to the bank only if there is a request from the employee to do so and until the employee revokes the request. Even if the request is made by the employee, the company is under no obligation to do so, and most companies will not comply.
Therefore, deducting on the instruction or request of the bank is out of the question unless the employer was a guarantor of the loan and is liable to pay it from their account and entitled to recover from the employee.
A lien on a bank account, whether it is a salary account or a savings account, does not concern the employer. In fact, I don't think there is any such concept. Banks do not give a lien on any account. What the employee does with the money in their salary account (which is essentially a normal bank savings account) is their concern, not the employer's.
If the bank needs to attach the employee's salary, they must approach the court and obtain orders from the court to do so (which the courts will likely be very reluctant to grant), only then does the employer need to act accordingly.
