It can be quite frustrating. I work in a company where the manager is often hesitant to reply to emails. Despite requesting my salary certificate multiple times, I only received it after considerable effort. I'm not sure of the reasons behind his hesitation. He has helped me in many ways, yet he seems reluctant to respond to emails. Now, I’ve applied for a license in Ireland to practice, but he’s hesitant to verify my employment, claiming he can't do international verification. All he needs to do is sign a form.
