It's becoming more of a trend for new hires to be expected to do their jobs starting on day one, even if this means having little to no training. While a lot of employers get away with this, it's often at a cost. Sure, new hires may be able to get through the day by learning as they go, but they aren't learning the ins and outs of how to be efficient with their work.
Proper training provides employees with the insider knowledge of how to optimally do their jobs. It's these shortcuts and tricks that can shorten a one-hour job to a 30-minute one. So, don't skimp on training. It's the key to getting more done.
