Realistic?????
There can be no other reason for keeping a remuneration package secret other than so you don't look stupid while negotiating with the workers, telling them there is no money for increases etc.
What about transparency? What KPI's were applied to achieve a bonus? What benchmarking is being applied to determine your worth?
Ever heard of accountability? Aren't shareholders (the staff) and stakeholders (the public, not just TAG) entitled to that?
