Can an employer say how much getting paid?

Yes, an employer can tell an employee how much they are getting paid. An employer is not required to keep an employee's salary confidential, and so they can tell the employee how much they are getting paid at any time. However, there may be some exceptions to this rule, such as if the employer has agreed to keep the employee's salary confidential, or if the employee is a union member and their salary is part of a collective bargaining agreement.
