The company I work at has this thing we have to say every morning. What is it called?
Solution 1:
The Company Credo. Merriam Webster says about credo:
Credo comes straight from the Latin word meaning "I believe", and is the first word of many religious credos, or creeds, such as the Apostles' Creed and the Nicene Creed. But the word can be applied to any guiding principle or set of principles. Of course, you may choose a different credo when you're 52 than when you're 19. But here is the credo of the writer H. L. Mencken, written after he had lived quite a few years: "I believe that it is better to tell the truth than to lie. I believe that it is better to be free than to be a slave. And I believe that it is better to know than to be ignorant".
Many thanks to @ThunderGuppy for suggesting a definition from Collins English Dictionary that fits the question better and acknowledges that a credo does not have to start with I believe.
A credo is a set of beliefs, principles, or opinions that strongly influence the way a person lives or works.
Solution 2:
This can be considered a mantra.
a word or phrase that is repeated often or that expresses someone's basic beliefs
[MW]
Typically a mantra is smaller, but the word evokes the kind of thoughtless droning mantra implies. I imagine this is the case in your office.
Solution 3:
This can be called pledge.
From Merriam-Webster:
PLEDGE (noun):
a binding promise or agreement to do or forbear.
a token, sign, or earnest of something else
Solution 4:
I would call this a company values statement. (Or possibly a vision statement.)
I wouldn't call it a mission statement or manifesto, because it doesn't define what the company does; only how it does it.
Nor would I call it a credo or mantra, because it doesn't list things that employees believe, only things that they do.
It could be a company pledge, vow, oath, or similar (as per other answers) — but if so, I'd expect everyone to be saying every line, all together.
(And you wouldn't get UK employees to spout this rubbish every morning without a lot of sarcasm…!)
Solution 5:
Every morning at work, we recite the company manifesto.
manifesto
a written statement of the beliefs, aims, and policies of an organization, especially a political party:
In the West, we use this mainly in political contexts, but from your description it sounds like this is not so removed from a political or religious situation.
