Sharing the loss usually comes in the form of layoffs and reduced hours.
Losses are shared between a company and the employee losing their job, income is (unevenly) shared between an employer and the employee, profit is exclusively for the employer.
Cuts to jobs and reduced hours can be because of losses, or they could also be due to efficiency gains, in which they could be related to profits instead. Divisions and jobs can be cut because they make neither profit or loss.
Employee's don't share in losses or profits unless their compensation is somehow tied to profits.
