When a company gets to a certain size, its employee base becomes ungainly, like abnormally corpulent testicles on a little man with chubby thighs, and he's trying to run to catch that elevator, but dammit, it's not going to happen. So many low-level plebes work for them, it's like a goatherd with too many damn goats in the field and they're all out there eating scrub brush and pebbles and shit and the goatherd doesn't like it. You hoary goats. So the goatherd has to think of a way to keep those goats in line. The answer is cheerleading. This no longer makes sense with the goat metaphor, which was really rickety to begin with.
Work for any major corporation on the ground floor in an environment with a fairly large number of other employees, be it a Staples or a McDonald's or whatever, and odds are you're going to be subjected to some manner of pre-shift meetings in which your manager gathers the crew together to let you know how awesome you're all doing. Except for this, this and this. But otherwise awesome! So awesome that maybe you can do better than yesterday today! Awesome! Go you! I am going to throat-fist your soul every day you work here until you quit, get fired or have to be institutionalized!
It's not a metaphor. Open up.
Nineteen percent of people apparently give a shit when their manager does this, though in fairness a percentage of that 19 percent are probably managers and people who are self-employed, so let's just assume 5 percent of workers like these cheerleader company meetings, and a high percentage of that 5 percent need their managers to re-pin their mittens at the end of said meetings.
HR people can't be so stupid as to believe that employees are motivated by hearing how much money the store is making, or how much more the store needs to make because of their lazy hides not working hard enough. There's no way to spin a "our success is your success" speech into something that doesn't sound like utter bullshit unless employees are getting a cut, and even when they are, it just means that they're generally forced into a position where they look at co-workers as competition rather than people in the same boat, so you're just as unhappy at work. If you are happy at work and don't feel this way at all, consider yourself lucky, and maybe also consider that everyone you work with may hate you.
