Svantaggi
Overall given the competitive job market and number of employment options in Northern Virginia I would personally consider working with Serco to have been somewhat of a career misstep. Even among federal contractors Serco has a tendency to significantly underpay. They will offer you the bare minimum of whatever your market rate may be. The organization as a whole and especially the HR department is poorly organized and constantly in a state of instability. Coming in I was met with a revolving door of coworkers, managers, and even executive leadership and when I eventually left a couple of years later the situation had not improved. Performance feedback is few and far between, often non-existent. Mid-level leadership is uncharismatic, apathetic, and sometimes outright disrespectful to employees and other management teams which reflects poorly on the HR department as a whole. There are major issues with under-staffing throughout the organization which creates high strain and high burnout. For the reasons listed above Serco has a bizarre, loosely formed organizational culture and high-performers tend to take other job opportunities within 2-4 years of working there because current leadership does not seem to value career growth or retaining talent. Despite needing to work closely with each other there is no team atmosphere and people who work there are generally unhappy and frustrated. Serco Group has had a number of extremely high profile and concerning controversies within the last 15 years involving humanitarian issues, insider trading, embezzlement, etc.
