Try to get a letter of recommendation from each employment-related reference whom you know will give you good marks. For example, Vice Presidents, Dept. Managers, Supervisors, Subordinates, Coworkers, Customers.
Naturally, potential employers might suspect that you targeted only favorable references to write each letter of recommendation. But employers still want to know that there are at least some people who have good things to write about you. It puts them at ease.
If you have little or no work experience, target favorable personal and character references to write a letter of recommendation for you. Professionals who know you well are most impressive.
