Always maintain the French work ethic:

• No communication outside work hours
• Dont care about the buissnes
• Dont care about the boss
• Never attend optional "teambuilding" exercises
• Don't do work outside work hours
• Use as many sick/vacation days as possible
• Always prioritize your mental and physical health above corporate profits

best practice is don't even respond. most people will get the message that you basically don't exist if you're not physically at work. and if not, fuckem

I'd reply "hey" back on Monday morning when the new shift starts.

work communication is for work. after 17:00 that shit gets turned off.

My boss got an earful yesterday when he called to ask me to come in to work, I was at a furry convention and a howl had started right after I said hello.

He was confused, I didn't elaborate, and I told him I wasn't coming in until June as I was on my vacation.

I actually love when my boss asks me to do shit afterhours but that's only because I get paid double time to do so, I have no life, and I can always just say no if I'm not the one scheduled to be on call at the time. It's amazing how if you pay people enough and treat them well then they are willing to do things for you. Funny how that works.

Nice attitude I guess
