Pro-tip: If you're a boss or manager, don't send email, Slacks, etc, outside of business hours. You might not intend them to be responded to until start of work, but it send a subtile message of "I'm working at 11pm or on the weekend, why aren't you?"
@grumpygamer it's like the boss who's like "we are chill about working hours here" but then they work 14-hour days and setting an example.
