Nope. Don't care in the slightest what others earn, what their job titles are, whose you-know-what they're sucking on - I keep myself to myself. Watching my peers just burn money like it's cheap firewood on crap and trinkets, I'm probably better off financially anyway
So if your peers were paid say 20k more than you for doing the same job you'd not be bothered?
I think a lot of managers would be very keen to know that, saves a bit of worry when dividing up the pay rises/bonus pool etc.. if they know one guy isn't bothered too much.
