What's missing
Where the app can't follow a rule to the letter yet, its notes say so, and say how to allow for it when you enter your hours. From this page's agreements:
- The app starts each year's rates on the state's issue date, as the agreement's own dates aren't published (the federal Davis-Bacon schedule dates the 2025 rate July 1 2025).
- Five 8-hour days only (no 4×10 rule is published), and there's no make-up day.
- Whether holidays are paid when not worked isn't stated (the state shows no vacation or holiday contribution), so the app pays nothing for them. The extra days aren't marked: a Thursday holiday makes the Friday a holiday too, and the Saturday after a Friday holiday and the Saturday before a Monday holiday are paid at the holiday rate, so tick Holiday on those days. When two holidays land on the same Friday (Christmas Eve and Christmas 2027, New Year's Eve and New Year's Day 2028), the app moves the second to the Monday after.
- The app takes 4% of gross wages, the highest flat percentage in the pilot locals' documents: type yours as the dues % on the Settings tab. There's no vacation fund.
- Shift premiums aren't published, so none are added.
Enter your own hours in the Pipefitter app: it applies these rates, the overtime and holiday rules, dues and tax, and keeps a year of paychecks. Free for a month.
Your agreement isn't here, or a number is wrong? Send us your agreement from the app's Settings tab. If the app doesn't have it yet, you get a free year when it's added.
