Is it permissible to take the full rights stipulated by law from the employer without his knowledge if he does not grant them to employees and is not trustworthy?

It is permissible for an employee to take his right without the employer's knowledge if they had agreed upon it, or if labor law compliant with Sharia (definition) guaranteed it and the employer denied it, and the employee found no other way to obtain it. This falls under the issue of "seizing one's right." However, if the employee anticipates the employer's denial and takes the money without his knowledge preemptively, this is not permissible; it is a form of consuming people's wealth unlawfully and a breach of trust.
