The lessons
Free to read, free to link to, free to send to somebody. No account, no paywall, ever.
The practice cards
Creative Commons Attribution-NonCommercial-ShareAlike 4.0. Copy them, print them, hand them out, use them in a library, a drop-in, a union branch or a classroom. You do not need to ask. You may not sell them.
What this is not
Nothing here is legal advice, financial advice or a substitute for your own organisation's rules. Where your employer's rule differs from something on this site, follow your employer's rule and ask why it differs.
Accuracy
I check every claim and I still get things wrong. If you find something wrong, tell me and I will fix it and note that I did. Corrections are published, not quietly edited.
