If you have a TM that's consistently not making performance goals, you need to document it in Workday. Essentially, most performance issues require 3 documented performance conversations before moving on to a corrective action (CCA). You need 3 CCAs of the same type for most things for a termination.
In the case of seasonal or probational TMs, anything warranting a single CCA is usually enough to term.
When writing the performance conversations, the important thing is to be thorough and to be professional and unemotional in your writing. Use facts and metrics; use expectations vs. what was accomplished. Follow the guide that's given on the top of the Workday page. It usually goes as follows: Behavior, impact, TM response, next steps.
"[TM], on [date], you failed to perform by doing [behavior/action].
This impacts the store by [lowering X metric, lowering guest satisfaction, causing use of additional payroll, loss of sales, etc.] (this always varies depending on the performance issue, ex. Slow UPH in OPU causes orders to back up and orders are late, resulting in lower guest satisfaction).
You said [TM response here]. (Usually I will add rebuttal to their response if I had any during the conversation, or any other comments here as well.)
Going forward/In the future/etc., ensure you do not perform [performance issue at hand]. Failure to do so could result in additional performance conversations, including corrective actions [or termination]."
Corrective is much longer and more thorough, and usually refers back to each written performance conversation that is relevant to the CCA. You usually need dates and such for each, but if you wrote your convos well that should be easy. This is then sent to your HRTL/ETL-HR for HR approval, and can be sent back to you if it needs changes. I'd recommend partnering with them before starting a CCA though so they're aware the process is beginning.
Essentially, performance issues are a 3 CCA then term thing, which sucks. It's effectively 9 full performance conversations and 3 approved CCAs.
Lastly, look up resources on the HR SharePoint. There is a performance conversations page, correctives page, examples PDFs, etc. Incredibly helpful. I had to get familiar as we were out an SD for a year and had a new HR. Some pages are role restricted, so ETL or HR may only be able to read certain documents.
