And if you work at a place as an employee that has made a situation where you ARN'T disposable, you should either try and change that or leave.

If there's a single point of failure like that, the company is being mismanaged. NOBODY leaving, getting sick, taking a holiday or even dying, should leave the rest of the company at risk.

Companies should most certainly value employees and treat us with respect, but they should also be setup to allow for employees not being around forever.
