Well, be diplomatic. Remind the manager politely but only once. don't talk to others about your eagerness and be positive. Also depends on the firm. In medium sized firms like Anjum Asim, Avais Hyder, energetic and intelligent ones usually spend an year stuck in the firm/jail due to high politics. If manager is revengeful, he might keep you indoors for longer periods. That's an indication that you are in trouble )
Just work hard and things would be fine. Happened to all of us D
