To think is a data breach - and out of order?

[YettaTessieMarmelstein]

I work for a large company everyone on mumsnet will have experience of. We get contacted by members of the public - usually to complain. They sometimes contact by text. I am working from home in a job that doesn’t usually involve the public. My line manager has told me, as well as my regular job, I have to reply to complaints by text using my own mobile. I have refused since there is no way for the person not to have my personal phone number. A colleague who did this received abusive texts late one Friday night.
I Also suspect my employer would be breaking GDPR rules by me having people’s phone numbers.
Can anyone shed any light?
I am not happy about this at all and I am wondering where I stand.

I’d purchase a separate pay as you go SIM and charge the costs back to the company through my expenses claim, although I have to say my employer would never expect us to do anything like that!

As for having the customers Phone numbers/data, don’t they have to give consent to you processing (using) their data? If they haven’t given specific permission for their number to be used in this way (a “tick to opt out box“ is not sufficient I believe, it has to be “yes I give consent”) then I think it could constitute a breach, yes but I am not an expert :)

Do you have a 2 SIM phone, Kinkybk?

Definitely not unreasonable, what the hell is your employer thinking?
