"[Name of my boss who I hate and think is useless]

"The person named above is taking part in the [Name of Place I Work] Development Programme and has nominated you to provide feedback for them.

"(...)The results will be collated along with other colleagues to produce a report for their personal development. Whilst the report will contain all the feedback you have provided, they will not be able to attribute ratings to individuals unless you were the only person in the group - for example, if you were the only member of their staff who gave feedback."

The key point is that last sentence. I WILL be the only person giving feedback so he'll blates know it's me so how can I tell him how shit he is without him getting all pissy with me?

no serious answers please.
