I thought they contracted out their entire staff? Seems that “keeping their workforce happy” goes against contracting. If you do a contract and you like the client, you might pick up another one. Otherwise no hard feelings, get the current contract done and go work for someone else.
That post doesn’t quite seem to imply that people just contract in and out like freelancers, but more that they are hired at a per hour rate on a permanent basis.
Instead it's a celebration of what made them great. A promise to keep their workforce happy. An idea of going agaisnt "growth at all costs".
Fantastic!
