I've noticed a pattern that many people don't use periods at the end of sentences in Slack messages (or text messages, really any short-form communication medium). I also tend to avoid periods during short communications because for some weird reason they come off to me as "harsh" or "abrupt". Almost as if the person has lost patience and is becoming snappy. I don't get that same feeling for longer form communication, but short messages ending in a period definitely come of as "short" to me. I think subconsciously the lack of adding a period is my way of conveying that, "I'm not trying to be short-tempered, and I'm not annoyed. This is just a quick and informal communication with all due respect still intended."
