I've got one person under me and have done for 3-5 years.

Most have enjoyed working under me (so I understand it), most resignations have been for bigger opportunities / bigger cities / bigger money (1 out of 4, and TBH I missed they wanted more money - this was my fault).

My current "report" seems very happy (though I expect them to leave soon, not for money but they are far more interested in another industry and tech challenges that come with it).
