Trainer/CoachCentric Network And Office Automation May 2001 - Aug 2001Training and coaching of dozens of new IT pros (Windows 2000). When the bubble started to show cracks here in the Netherlands, less project were available for the outsourcing company I worked for (see previous 5 jobs). Personally I was still able to pick jobs, but for many of my colleagues and new employees (the work force was still being expanded) there wasn’t much work available. I was offered the position "trainer/coach", which meant I had to coach and train employees that currently weren’t outsourced. This included selecting and advising education and career paths, as well as training and coaching people to pass the Windows 2000 MCSE exams. -
