It really isn't that difficult to comprehend when & when not to use the reply all function, but for some reason BNY Mellon is full of mo--ns that lack such comprehension skills.
If the company would have adopted a policy to automatically rate these mo--ns as needs improvement, perhaps this company wouldn't suck as bad as it does.
I hope I am the next person on the list to get displaced, but the smart thing would be to use displacements to get rid of these mo--ns.
Outlook even gives a warning message when there are a high number of recipients, and yet it is still a monthly occurrence to have multiple people use reply all to say they got an email by mistake.
