Do you guys worry about your non disclosure agreements at work? I use my personal computer at work so I do my own projects on the same computer as work but it makes me a bit uneasy. We're a broke startup and I'm lucky to have the job so I'm not going to ask for a computer.

Also, are you aware of it when you make rants- trying not to be too specific? Or are you not worried?

I refused to sign ours. It was a standard NDA, which I would have been OK with, but the boss hid a clause in the middle saying if we left the company for *any* reason (quit or fired), we would be responsible for repaying the company back 100% for any on-the-job training. That included 'training' subscriptions like Pluralsight, off-site 'training' like MS-Build (including travel $$), etc. Myself and the web team mgr are the only ones who caught it. If she didn't also refuse to sign it, I would have likely been fired. Also helped she is good friends with the CEO's wife. Boss decided not to push the 'sign or be fired' chest pounding performance after he found out.
Boss: "You'll sign it or be fired!"
Me: "Kelly said she's not signing the NDA either. When she talked to Barbara about it, she was going ask Bill about the legality of the contract"
Boss: "The CEO!?....oh frack...leave my office...just fracking leave."

@PaperTrail that is illegal. report him to HR. any training the company provides in order to teach you something for your work should be paid for by the company.
Broke startups, and using your own computer means that thier NDA is not enforceable. just don't anything too dumb and traceable to you, and you will be fine. same thing goes for rants.

@magicMirror The secret addition was removed not long after and a more realistic NDA was proposed. I didn't sign it either. There was a clause about not taking a job with a direct competitor within 6 month of leaving the company (we have *a lot* of insider knowledge a direct competitor would love).
When I asked our HR rep about it's legality he said the company can tell you that you can't take a job, but legally can't enforce anything.
Me: "What if I don't sign? Will I be fired?"
HR: "No, the document, signed or not, goes in a folder in the big cabinet. No one knows but you and I. If 'John' wants to see that document, he has to get approval from the board to see private employee contract records. I never see that happening. 'John' is the only one who pushed the issue after someone made it known about the training pay-back clause. We told him it wasn't enforceable and if we tried, a call to the state auditor could get us in a lot of trouble."

@PaperTrail Here, the standard contract contain two points. one, a non-compete, meaning you cannot go and work for a competitor for X time period, and the second, is not to try and recruit other employees after you leave the company for X period of time. Both are only enforced very rarely. I never heard of those actually enforced, in all my time working in the industry.

Keep the work projects in a VeraCrypt container to be sure no one can steal it..

Crypto is always good

I always fiercely negotiate my NDAs.

I've had companies try to steal the legal rights to projects I've done on the weekends, ideas I've had for things far outside of their industry, or tell me I can't discuss or share ANYTHING with non-employees, even public-facing things like CSS or JS code.

The latter makes finding another job soo much harder. (Which, I suspect, is why it was written in such a way.)

No, I never let any of that make it into any contract I sign.
