107 certified Labor Condition Applications on file with the U.S. Department of Labor, FY2021–FY2022.
Since September 2025, DOL's Project Firewall opens H-1B investigations without waiting for a complaint. These checkpoints come from Slack Technologies, Inc.'s own public LCA filings (FY2020–FY2022) — the same records an investigator pulls first.
Each worksite needs its own 10-business-day LCA notice and a PAF record of that posting; a move to a new area of intended employment needs a new LCA before the worker starts there.
Level I is the entry-level prevailing-wage tier and the band DOL's Project Firewall reviews first for misclassification (senior duties filed at an entry-level wage). The national share is 17%.
No additional recruitment or non-displacement attestations apply.
Public DOL disclosure data can lag actual filings by a quarter. Descriptive only — not legal advice.
