While we tend to think of it as entertainment, it goes beyond that

I am unable to think of it otherwise :)

I don't think much of companies that incorporate the storytelling method for greater effectiveness. As long as that company is not an intimate part of those who work there, such methods are, for me, merely a means to an end to make employees believe that the company is something like family. Which it usually is not.
The very nature of employment relationships contradicts such methodology. Employees sign contracts and there the hierarchy is clearly regulated and the employee is bound by instructions and otherwise has no say in the running of the company, no share in its profits and of course no share in its losses. From this point of view, this existence contradicts the model of a family, where all profits and losses are shared or are the responsibility of the family. Where companies give themselves profiles and their corporate policy pretends to be a family environment, they certainly succeed in doing so, so people always like to identify with their employer, because otherwise they have few comparable identities that take up as much energy and capacity as work.

A shared enduring narrative is not authentic in this environment, as births and deaths within the workforce, for example, are basically just disruptive, as employers are not willing to compensate for such things, but it has economic disadvantages for them. However, a culture that cannot or does not want to absorb birth, death, illness is therefore not an authentic environment, so a company's story is only really of value if the company includes such things and really shows itself as a family. Where the management attends the funeral or welcomes children to the company, etc., where there is shared mourning for tragedies and shared celebrations for happy occasions, so everyone knows everyone well. But it is not like that and the concept of gainful employment and taxes and money-regulated professions with a strong division of labour has nothing to do with family, rather it has led to the destruction of the family or to its degeneration. At work you are an individual trying to assert yourself against other individuals who are in competition with you and where you submit to a leadership that gives you your tasks. Exceptions confirm the rule.

I have been a PR consultant for a long time and I know the methods of corporate and brand PR. They all live on emotional charges and the constant repetition of their "brand and corporate values" that you just made up. There is nothing behind it, people come and go and nobody stays anywhere for several years or even decades. Nothing can grow that could be called a really good narrative. They are decals of an era far in the past that are used for the present, the whole thing lives on nostalgia and the ideal. This can also be seen in classic product advertising. ... without the peoples, a narrative is not worth much.

But of course, for the banal everyday life, it is perhaps good to convince oneself that one is working in a working environment that offers some narrative instead of none at all.
