Isn't the whole point of a SB, is that noone knows it is you? If the only Q's in the box are from you, then this says more about your colleagues, than you dunnit?
The Qs seem reasonable enough to me, and they appear to have garnered the usual management responses.
1. Nobody is going to say 'yes I had a pay rise when noone else did' so token answer: nobody did "that I am aware of"
2. Yes we'll look into, maybe next year, maybe manyana.
3. Yes, far too expensive on the company overheads. Get rid.
