It is common in the UK and normally they are well thought out and have balanced benefit for both parties. I did dodge a bullet once in my career though where a bunch of mid level devs were proposed a course to take them to senior (and a 5% raise) but it came with a 2.5 year retainer.

I read all the docs carefully and I wasn't convinced by the course content so didn't take it. On the day the course was to begin, one manager pulled me to one side and said they really value me and would offer me a 8% raise—but I had to take it right now—he even had an amended contract and pen in his hand, open on the last page for me to sign then and there. I refused. I was seen as a bit of black sheep by management afterwards and sidelined.

Every dev that took it came to me over the course of the next few weeks and said they wished they hadn't taken it as they didn't learn anything they didn't already know and they felt like they'd been cheated. They could get out, but they'd owe the company something like £7,000 which gradually reduced each month over the course of the retainer.

It was a tactic to stem the flow on the revolving door that place had. The weird part is although technically and ethically it's by far the worst place I ever worked, I made so many friends there and the people were truly amazing.

Eight years later I'm still in frequent contact with several of them and we often reminisce and recall the crazy stuff that happened at that strange place on an almost daily basis. Looking back now it's almost comical, like something straight out of a Dilbert nightmare. But the stress at the time was immense.

By 'course', I had assumed the parent meant something valuable: a degree, masters, PhD or well-recognised certification, such as PRINCE2. But reading your comment, and again that of the parent, I'm now not so sure!

Anyway, my point is that my response had made those assumptions, as that's the kind of arrangement I know is common.
