I have recently been made aware of an employee who was transparent to her manager in Summer 2023 that she was permanently moving to Portugal to live. This wasn't picked up as an issue and no contractual changes were made. She teaches online... however, contractually she is based at one of our bases in the UK and no contractual changes have been made. Her contact details in our HR system still show her as living in the UK.

I realise this isn't sustainable and presents risk for us as a business and her as an employee therefore and we potentially need to terminate her contract however, I am unsure on what basis - has anyone else had experience of this? Any advice appreciated.

Thank you.
