Rebecca received the following e-mail from her boss: i need all employees to work late on saturday. no exceptions! what is the most likely reason why this communication is not effective?

Well for one it's in caps so it makes it seem like he's angry and also kinda rude how it doesn't message all of them separately asking who can and can't come into work, saying he needs as many people as possible. Not only that but he says no exceptions which seems greedy and inconsiderate.

Because the internet has no self-respect and everybody is desperate for short-lived attention to become a stupid meme.

B, it is easy to scan for key information. there are times when a lot of information is included in a business letter. the block letter format you find key bits of information quickly, without having to read through the whole paper.
