It is a good practice in many 'single shift' organizations to have all employees (including managers) reporting in time in the morning, so that managers can take stock of available resources, schedule work & allocate tasks. In such a scenario, there is no fixed time for the Managers to call off the day, though their subordinates (at workers level) break off at a fixed timing (unless some are required to work on a paid overtime basis). The point to observe here is that there is no concept of overtime for managers. But if the managers are not punctual in the morning, there is an apparent delay in the commencement of work in that department.
To that extent, your principal office at Singapore seem justified in asking all managers to report in time. And to introduce this culture of punctuality, your Head of Indian operations (and not the HR) has to drive this change.
