Do Not submit/click acknowledge in Workday until you write your comments/rebuttal. Writing and thinking through what your comments/rebuttal are, why you disagree with the low rating, proof or examples of why you shouldn't be low rated, etc. may take a few days to write. But it's important that you do NOT simply click submit/acknowledge, else Silence is acceptance, agreement and participation.
Can your ratings be changed at this point or after your rebuttal comments ? NO. But at least there will be a record of why the Ratings are wrong or unfair. This has probation value for the future.
If you foolishly/Stvipidly already clicked Submit/Acknowledge, your other option is to STILL write the comments/rebuttal. Again, it may take a few days to write but it will be valuable and cathartic.
Email the finalized rebuttal version to your HR Business Partner, located at the bottom of your name in the Global Directory. If you have No designated HR Business Partner, Open a Case/Ticket in Workday and send it that way. Again, at least there will be a record of why the Ratings are wrong or unfair. This has probation value for the future. I would even send it to cc, Sara Wechter and go that high up !
Be aware that HR in any company works for the company/employer and NEVER for the employees. HR, Legal Dept., Compliance Dept., etc. do NOT work for the CEO, much less the lowly employees. Regardless, write and send the rebuttal email as detailed above.
