Comment on why the behavioural change program will not be successful in the below paragraph:

Following one of your presentations, two workers separately ask to speak to you in confidence. One worker tells you that they were seriously injured six months ago, because of a non$-$work$-$related accident, which means that they now need to use a wheelchair. They go on to say that they returned to full$-$time work two months ago without a phased return to work. Their supervisor refused to allow them to return to their usual job on the shopfloor, citing 'safety concerns'. However, the worker was assessed as medically fit to return to their previous job, but some modifications would be needed. They tell you that they had been placed in the office and had been given administration tasks, with a promise that they could return to their normal role within a few months. This has not happened. They also find it difficult to open heavy doors around the site.
