Saw this sign recently. It is an excellent example of why the apostrophe is the most underappreciated punctuation mark in the English language. Unlike commas and semi-colons that are over-rated the apostrophe is often overlooked. Omitting one tiny little apostrophe drastically changed the meaning of the sign. Of course the author of the sign could be taunting potential employees that they no are longer are hiring. That would be an interesting approach to recruiting staff. However, I think the author probably meant “We’re hiring” or “we are hiring”
