And contractually, any code I made was my employer's if I made it during office hours. Some even made a claim for code I would've written that during my employ that would be "competitive". Luckily, there was a massive difference in what I would do in my own time versus what they did.
Some agencies do, however; it's dependent on the contract specifics.
When I'm hired in a company (not contract), they wipe the harddrive when I leave (well, I also do it before I hand it over sometimes). So they don't get the tools (I take them with myself, it would be a waste to loose them)
As per NDAs and work contracts, nothing is supposed to leave either employer nor customer systems into unauthorised third parties.
