Remote Working

Job ID: 33542507

Budget: £20 – £250 GBP

My partner is currently working for a social media company in London and has done for over 3 years.
They have recently said they would consider remote working for some employees. We would very much like to move to Portugal n in Spring 2023. The manager has advised he puts a proposal together on how working remotely will enhance his success in the role. He needs to sell the idea basically. I wondered if anyone has the experience of putting together a proposal like this with success ?
Thanks very much
