Let's face it, JB's been missing in action for months, a CEO in name only.
Staff can't wait for him to announce his resignation for whatever bull**** reason. (spend more time with family, pursue other opportunities, blah blah blah)
It's to be hoped that the damage he has caused during his tenure can be repaired, but it may be too little too late.
There will certainly be a lift in morale once JT assumes the role but unless there is any real substance associated with the change, that morale boost will be shortlived.
