DonDraper,
There are a lot of logotypes that look like this. Even I have one that looks similar (http://stocklogos.com/node/2595). I created it back in 2004 as part of a proposition for a real estate agency (they decided to go for another idea of mine, so it was left unused and I submitted it here with a fictive name). I don't think this one is a deliberate copy of the workopolis logotype, it's just very hard to come up with new ideas while using simple geometrical forms.. :)
