My sister has had issues with her company before regarding a data breach. (They forward a letter to various employees which had her address on it)
She is currently shielding until the end of March.
She received an email from the company today saying that furlough is being extended, but this email had clearly gone to over 100 people at the company with their home email addresses all shown.
She has had enough and intends to hand in her notice next week anyway as they have been an awful company to work for.
She is considering making a complaint about this but her DH doesn’t think it’s much of an issue.
