Is this bad?

[FrameyMcFrame]

I am possibly being made redundant and am at the start of a 45 day consultation.

I emailed HR and the two managers of a programme I work on with questions regarding my contracts and redundancy etc

One of the managers responded to me but I found out from my friend and colleague that she had BCC'd in another member of staff who is on my pay grade and does the same job as me!

She alerted me to this and asked did I know she was bcc'd in?

I feel really upset that my confidentiality has been breached and I'm also wondering who else she included?

Is this bad, and should I inform anyone that this happened?

Hmm yes I would be annoyed. Who is this colleague who was bcc'd? Are they in your team? They definitely shouldn't include someone in your direct team at your level. Are they in HR? Being on the same pay grade isn't necessarily the problem.
Are they in your team? Can you think of any reason why they might want to know? Finance manager / payroll clerk who has access to your salary etc who might need to know you've emailed? Have you asked why they were bcc'd?

Tbh, everyone should have been cc'd. If the person had a right to know there would been no need to hide them.

I would be cross

Yes they're in my team!

I think they had been having a conversation about the same issue but even so, I'm upset that she shared my personal redundancy information with another employee

Also, I don't know who else she bcc'd in.

Not sure what to do now, but I certainly don't want any responses that cone back on that email thread to be shared with others

I think that's really bad and I would definitely raise it. That's personal information and no one should have been BCC'd in let alone a direct colleague on similar terms.

Oh wow if it's someone in your team I would not let that go.
Using bcc is so sneaky. If you ever have to use it you shouldn't be including that person in the first place in my opinion!

What would be the best way to handle it?
