Changes are imminent - whether it is the top man or at different levels. Every time, organizational change occurs particulary at top level, it is certain that the new management will review policies in all respects. People want to leave their imprint by thinking differently and this is one of the reason for shuffling of positions in any organization.
Depending upon the knowledge, experience, interests and targets of the person taking charge, and also the advise provided by down under, unless otherwise it is one-man army as in small organizations, the policy shift can be either good or bad to the organization (and to the subordinates?). It may take sometime to see the results of these changes.
As per rules, whenever the occupier or safety in-charge changes, this information needs to be informed to regulators immediately. And, it is better if regulators keep a watch on the affairs of such organization(s) for a reasonable period, to ensure that the safety issues continue to get top priority inspite of the changes in the organization.
