Does using available school resources (computer, internet, printer) to enhance personal and professional development constitute an infringement on public funds, especially given that the goal is to improve job performance and transfer knowledge to students?

If the devices are used for training and improving the teachers' performance, then there is no harm in using them. However, if they are designated for another purpose, it is not permissible to use them, as it constitutes an encroachment upon the entity. Teachers have the right to demand their entitlement to ensure the activation of the service available to them.
