I just read an article which supports my theory that even though Kronos has downsized and not grown so much recently, they are still the market leader by FAR with what, 30k clients? They are also in an excellent position to challenge the ERP vendors in the workforce management arena given all the acquisitions in the past few years. I mean, we've got not only the traditional Workforce Central stuff like Timekeeping, Accruals, Leave, Attendance & Scheduling. Now there's a slowly improving HR/Payroll package, a bit of recruiting/talent management and other bits that snip at the heels of PeopleSoft and SAP.
It's a good read. Check it out.
