How many times have you wished you could tell your boss exactly what you think of him? Dr Raj Persaud hears about "360degree feedback", a work assessment system which enables you to do just that. Be prepared to be on the 360-degree feedback receiving end, though, too. Producer Marya Burgess

Feedback at work is a great idea but are there dangers in a system where everyone gets to speak their mind?

All in the Mind 4.30pm R4
Imagine the scene: you've been working at a large company for several years. You feel your talents are underused and that you could do your boss's job, no sweat. And as for that waste of space that's been sitting next to you for the past two years, he should have been pushed out the month after he joined. And then your company introduces an appraisal system called 360-degree feedback. You're sent a confidential questionnaire on your boss and your hopeless colleague, asking you, at long last, to rate their performances through a sequence of questions. Sweet justice. The only hitch is, your boss and your colleague will be rating you, too. And guess what? Your boss thinks you're belligerent and lazy, your co-worker finds you rude and uncooperative. It's all about perception and reality, you see, which, as Dr Raj Persaud explains today, is fine in an open company but damaging in one where there an atmosphere of mistrust.

Dr Mark Porter on sperm-donor anonymity: page 40

The Commission 8.00pm R4
In the latest of Radio 4's very own public inquiries, Nick Ross and a panel of experts ask if sperm donors should be identified. In a poll commissioned by the Children's Society earlier this year, more than 75% of people questioned thought children born using donated sperm or eggs should have a right to know their genetic history when they reached 18. Could this mean a decline in voluntary donations for childless couples, though? Read what Dr Mark Porter has to say on page 40.
