So true and applies at every level. Part of the reason that it is the big things that come out is that anything less they learn to live with because it was dismissed.
If someone feels unheard with the little things – my office it was temperature, yours will be different – then how do you demonstrate that you will stand up for your employees. And if your employee doesn’t trust you to understand and deal with and innocently meant but hurtful comment. Then they probably don’t trust you to deal with the intentional discrimination.
By the time you do listen, something really bad will have happened. You will probably lose someone who was a good employee. You might be facing a law suit. The behaviour will be endemic and hard to change.
If you’re lucky that brace person tells you and you realise, before it’s the tip of an iceberg.
