I'm a UK employer with around 50 employees in the business, with 6 in the dev team. The sales team are mostly remote and whilst my development team are office based I'm not that worried where they're based as long as they get the job done. Our head office is oop north and the dev team down south anyway so there is already an element of remote working involved.
However I've yet to see anyone make a truly compelling case for routine remote working. My developers tried it when we first started the business and really didn't like it. They missed being in an environment dedicated to work with no kids running around downstairs and also the social aspects of being part of a team physically sat in the same room.
I'm recruiting at the moment for a new web developer (good all round skills required in PHP and / or Node, general experience with SQL databases) so if someone can convince me they can do the job remotely then I'm all ears.
