Hi. I was recently sacked from my job of over 10 years (performance related dismissal). However within minutes of being sacked I started to receive messages from colleagues and it immediately became apparent that they had not just been told I was sacked, but they were told the exact reasons for my dismissal. They were not my managers nor would their work be affected by my leaving, so I don't see any reason why they need to know the reason for my dismissal.
Obviously I am still feeling a bit of shock over being sacked so I don't know if I am being oversensitive, but can anyone advise if it is normal to tell people the reasons for their colleague being sacked or if this is a breach of GDPR since the reason for my dismissal is my personal information?
