First off, I am not the OP. But I speak from the prespective as an Operations Manager who deals with client and customer complaints. When I am working off shore I do feel in a better position to be able to tell the wronged party, once we have established that their complaint in upheld, what we have done about it. This makes them feel heard, understood and gives them greater confidance that something has been done about the matter. By contrast, when dealing with an issue in the UK I am limited as to what I am allowed to say. I am not able to give the wronged party and real information other then a general assurance that the matter will be dealt with. This makes it harder to regain customer confidance.
Wow, that couldn't read more like management speak from someone who seems like they take pleasure from the disciplinary procedure if you tried. It also nicely explains your attitude to staff in your posts.
I can see no way in which knowing "staff member received a warning" is anymore useful than "action has been taken". It seems like its nothing more than trying to take a head. Look at me, my complaint got someone sacked, I'm the big man...
