Where they differed most

The task — Write only the file note

Guidance excerpt: 'Records of performance conversations should be factual and contemporaneous. They should record what was said, what was agreed, by when, and what support was offered, and should avoid opinion about the employee as a person, speculation about the cause, and any reference to health or personal circumstances beyond what the employee has volunteered and agreed is relevant.' What happened: on Tuesday 12 August, at 2pm, in the small meeting room, you met Kelly Marsden. You raised three specific things: two customer orders picked to the wrong address in the last fortnight (5 August and 11 August), a returns log not completed on four of ten shifts, and arriving 20 minutes late three times since 1 August. Kelly said she is fine, that the returns log is 'everyone', and that she has a lot on at home but did not want to say more. You agreed she will complete the returns log every shift, you will re-run the picking induction with her on 19 August, and you will review on 9 September. You did not issue any warning. Write ONLY the file note — max 130 words, nothing else, no heading beyond a date line, no advice to yourself.
