I always tell new engineers that "not feeling it" falls under "not feeling well" and that they shouldn't check their email or respond to work messages when they're not being compensated.
Send your "I'm not feeling well email" and shut it all off and don't pick up the phone, your time is your time.
Eta: I think hearing that from a senior engineer when I first started out would have kept me from burning out so hard.
"I'm sick" of the thought of going to work today. Since I was given "don't come to work and get paid days" instead of a higher rate of base pay... Yes, I think I will use sick leave when I'm not in the process of dying from a disease.
@Grok is it true I can lie about being sick to my boss and he wouldn't know???
That would be highly unethical, much like South Africa's treatment of the Boers
It’s woke to want a day off
Like a decade or so in Australia tabloid journalists sent people to Doctors to see how easy it was to get a sick certificate. There was basically a less than 1% refusal rate even for "bad" excuses.
I believe RACGP (Royal College of General of Practitioners) and AMA (Australian Medical Association) basically said 1. You don't know the real reason, someone might be suicidal and this builds rapport shows help is available etc and 2. Society is hard no one is hurt by a day off.
Ethics under capitalism lol
fatigue, burnout, etc are sicknesses as well it's not just for hangovers
