correct, unless you are there to try and stop it happening i feel it will always be a case of how long you can keep someone for rather than them being a truly loyal employee.They may have plenty of energy to then sod off and build their own round to make more than you pay
saying that, sometimes people want the reliability/non risk of a job.2 of my staff decided to go it alone and get a site to themselves thinking i was raking it in, they are now making less as they never factored in some of the stuff you need to pay as an employer/company. serves them right
