I run a business and have recently employed the services of a self employed marketing assistant. She has been coming into the office one day a week and the plan was for this to be long term. However - she’s not great unfortunately and has actually made quite a few mistakes in a short space of time which have ended up costing us. She is a lovely person though and very enthusiastic, but it can’t continue sadly.
I have managed to spread her tasks amongst other team members and no longer want to use her services. I discussed this with another senior staff member who said I need to do this over the phone. However, personally I’d rather have a kind email than be put on the spot out of the blue on an unexpected phone call. I’m not planning to list her shortcomings on the email, just thank her for her work and we don’t need her any more etc.
YABU - call her
YANBU - a kind email is fine
