Enhancing Employee Engagement in Training Programs
To add to the comments already made here, people will not attend training if it is of no value or interest to them. You can lead a horse to water, but you cannot make it drink.
Other than essential safety and operational training, no other training should be offered if it is not backed up by a sound Training Needs Analysis. If training is to be conducted, it should be what staff NEED, not what you or management THINK they need.
Secondly, it needs to be proper training, conducted by a trainer qualified to deliver the course. I have discussed at length many times here on CiteHR the problem of people just asking for generic PowerPoint presentations for training. Standing in front of a group of people and just reading off the words of someone else's PowerPoint designed for some other organization IS NOT TRAINING. All effective training must be designed for the specific organization.
There will always be a hardcore of staff members in any organization who will resist training. That's a given. Forcing them only reinforces the resistance. As others have said, there needs to be incentives, a carrot and stick approach if you will.
Training works well when it is enjoyable, fun, and employees see real benefit from it. If you can get the staff enthused about training, and a good trainer can do this, then the rest is easy.
I know this works from my own experience. I have enjoyed training courses where the trainer was dynamic, enthusiastic, and involved the staff in the training. That is the approach I use when I train people, and the survey sheets have always shown how much people enjoyed my training courses.
To give an example, some years ago, I trained about five groups of former staff of an airline that went bankrupt. They were mostly Flight Attendants who had worked all their life for the airline and now had to find new jobs. These people did training almost every week of their working life, in safety, customer service, airline operations, etc. Almost every single person at the end of the course told me that after 20 or 30 years of continuous training, they enjoyed my training course better than any other they had attended in their lives!
