Schengen visa officials try to let all genuine tourists and business travelers in and to keep all illegal immigrants out. But of course they cannot really know what an applicant plans to do. Perhaps not even the applicant really knows if he or she will leave again or not.
So they look for three things:
- Who pays for the trip and why? That's the same for you and for the colleagues who got their visa, so apparently it wasn't the problem.
- What are the reasons for the applicant to return? The best reason is a stable, well-paid job. Somewhat helpful are dependents who do not travel with you. They're a reason to return, but they might also be a reason to stay in Europe and work illegally.
- What is the travel history? Having been in Europe and not having overstayed is good, any incidents are bad.
So you should think if you have documented your circumstances at home properly before you reapply.
