Except don’t do this if your company tells you not to(which they most likely have) as it will actually screw you over pretty badly. Unless you’ve got hard proof of illegality going on, don’t piss off your employer by being paranoid.
The two things I can think of are the company may try to tag you for inappropriately handling what they consider confidential information -- and if something goes to court and the email ends up in the discovery process, opposing council may be allowed access to your entire personal email account.
It's probably better to copy everything as an attachment to a dedicated portable drive so it's less likely to be called out by the company, and if it ends up it court you only need to release the information on that drive.
Copying to an external drive would be way worse than using your own email. With the email you can prove that that was the only data you moved to outside the company. With an external drive they'd argue that it might be a habit, question what else you moved and sue the fuck out of you for breach of contract + violations of NDAs.
If it made the boss feel inadequate, then yes - dial that shit back, maybe pretend to attempt to roll but then trip (while actually aiming to just trip), roll for constitution to avoid damage. Taking ego damage is unavoidable in that case, except getting to keep the job more than balances it out:-).
And congratulations - you just leveled up! Now you get to do 1.1x your previous workload, for 1.00x your previous pay.:-( Although when all your friends at work get let go, you get to stay.
I quit my last job without notice because I had one lined up (but it turned out I couldn't start immediately) and in retrospect my rent situation would have been a lot better if I'd just scrupulously covered my ass for a month. And I'm lucky enough to have the kind of job where people call back within 12h of me submitting a resume but that's exactly because I do the kind of 100% essential jobs that have a coinflip's worth of shitty bosses and the kind of pay that leaves you paycheck to paycheck if you've had bad enough luck and/or life choices in a particular year. I guess I could've just called places and got some temp work from the first employer to offer but then I'm still having to cover my ass but now against the devil I don't know while learning a whole new set of policies that I'm only gonna use for one month before I'm learning the next ones. If you're in a secure enough position in your life that you can just quit because you have a good enough balance of savings and demand for your skillset then please take a moment today and practice gratitude to whatever entity or lack thereof that you attribute your good fortune to.
Oh I know. When you're raised by a narcissist with an obsession for controlling people, EVERYTHING is your fault. Never theirs.
Hey, did you know I'm responsible for my dads marriage failing, my school (a catholic elementary school) rejecting me (an athiest) for MC Hammer dancing in church (I was acting out a death scene portraying the lies of the church killing me), the holocaust, the dinosaurs dying, getting cancer, being fat as a 5 year old, my mom attempting suicide and going into a coma, having hearing problems, being born with the umbilical cord wrapped around my neck, my dad running himself over with his truck on a day I wasn't home, cats invading our home.....now granted I fully welcomed it, but I had nothing to do with it. Three of kittens LOVED me! And then he sent them to a kill shelter, because the no kill shelter was a 10 minute longer drive.
