I run a support department for a SaaS product and we’re lean. Everything is fine unless someone is sick or wants to take vacation. Of course hiring another person is never the answer according to the budget gods.
That doesn't sound "fine" to me. People get sick. Vacations are necessities.
Ended up with some. Am healing. Will be OK.
A decade ago many asked, "where is the new blood?" Could see it coming. Right now, people aging and burning out are super expensive to replace. In some ways they can't be.
I consider failure to manage this kind of debt severe. When it comes due, it is brutal.
