Build your workplace evidence checklist.
Pick what fits your situation and print the result. Nothing you select here is sent anywhere or stored. This is an organizational aid, not legal advice, and it never tells you to take material you are not entitled to keep.
Why preserve evidence early
Workplace records disappear quickly: badge logs and schedules cycle out, chat threads get purged on retention timers, and your own account access usually ends the day employment does. The safest habit is simple, preserving your own records, lawfully, as events happen.
Two rules keep preservation safe. First, keep only what you received or created in the ordinary course of your work, never someone else's files, privileged material, or bulk downloads. Second, store copies at home, not on employer systems.
What this checklist is not
It does not assess whether you have a case, and a complete folder does not create one; the law, the facts, and the deadlines do. If any of this feels close to your situation, the reliable next step is a private review. Deadlines can be shorter than people expect; see the filing deadlines by state.
