Hi hhurmade,
Though most organizations do not allow nor encourage dual employment, there are a few that have policies allowing such practice. In one of the organizations where I have worked before, they did have a provision for dual employment, subject to approval from the department head and the HR.
They review the second job profile and evaluate if that role would have any negative impact on the employee's current position. If everything checks out, they approve the second employment. However, I don't think there is any law that prevents a person from working in a private firm and taking up a second job, whether as a consultant or a full-timer. If the individual is employed by a government organization, the law strictly prohibits a second job.
In the case of government-funded organizations, depending on the nature of the entity, there may be provisions allowed.
