That's not what I asked. If I were to email a specific support person at ERCC, and say I need to know if support will be female only and specifically ask that there are no biological males, and they discuss my email among themselves and put it in a folder marked "TERF shit", maybe send an all staff email about it, is that also a breach of my personal sensitive data? I didn't give them consent to process it in that way. DPA isn't just for employers.
Sorry misunderstood
Discussing it with another support staff or with a manager how to respond - no breach.
All staff email naming you - breach
All staff email setting out your request but keeping it anonymous with a suggested standard response - unlikely to breach provided it was sufficiently anonymised - unlikely to breach.
Folder marked “TERF Shit” - unprofessional and more likely discrimination rather than DPA/GDPR. So potential disciplinary.
