Pluspunten
Very stable company with strong fundamentals. Great CEO in Carlos Rodriguez. Market leader in Payroll and ADP is working to use that to leverage market share in other areas of HCM. Very good benefits. If you are good and lucky, you maybe able to telecommute.
Minpunten
If you are in an individual contributor role, kiss your work life balance goodbye. Average hours range from 50 - 70 hours a week, depending on which area you work or which projects you work on. Career growth is slow. You seldom get promoted on your own, unless you demand and ask for it, and keep asking for it. ADP is not the best paymaster around. Currently undergoing a massive re-org, but hopefully it should be a lot more stable in a few years, but I somehow doubt it. Work/Life balance is non existent as the individual contributor roles are stretched beyond max, while bloat exists aplenty in middle management. There was a great opportunity to cut down on the bloat during the current re-org, but guess where the cuts happened?
