Is a company entitled to deduct the value of the remaining period of health insurance from an employee's dues upon termination of service, especially if the employee was not informed of this procedure in advance?

The ruling on these matters refers to the clauses of the contract between the company and the employee. If the contract does not stipulate a ruling for them, then reference is made to the prevailing custom or labor law. Its clauses are binding on both parties, unless the specific contract stipulates otherwise and mutual agreement is reached on that.
