Some ChangeManagement consultants are skilled in TurnAroundManagement. Corporations under stress can get assistance to "turn a new leaf" and meet the needs of all stakeholders, including shareholders and employees.
There is a "TurnAroundManagementAssociation (TMA)" (http://www.turnaround.org) which focus on "CorporateRenewal". Unfortunately a closer examination of their membership and objectives reveal a
concentration for bankcrupcy/liquidation/takeover/venture capital funding type of activities. So employee needs are probably out of scope.
OTOH, the overview of TMA is worth viewing as it correctly identifies the "existing Management team" as a possible source of the problem.
