Are salaries considered lawful or unlawful in cases where employees have no actual work due to administrative changes, and if unlawful, is donating the amount after repentance sufficient?

An employee, whether working for the state or for companies, is considered a private hireling who is entitled to the full wage upon delivering himself to the hirer, even if there is no work. This is because a private hireling deserves the wage by making himself available for the duration, even if he does not perform work. Therefore, as long as the employee makes his time available to the employer and adheres to the agreed-upon working hours, he is entitled to his full salary. If an employee leaves during working hours due to a lack of work, there is no blame on him if it is with explicit or customary permission. Otherwise, he must adhere to the working hours agreed upon in the contract.
