How to deal with receiving an interview notice from a new company at work?

Explain to the HR at your new unit that your working hours are not convenient for interviews. Ask if you can schedule a time when you are free, and they will understand and arrange it.

You shouldn’t feel like this either, seize the opportunity when you have it. Now is the era of self-sufficiency. No unit will retain employees, hire them as needed, and lay them off if they are no longer needed. Therefore, workers do not need to show loyalty and should act in accordance with their personal interests.
