For contractors, Login.gov has a default 45 hour cap on hours worked per week.
There are resources on GSA InSite
The TTS Handbook has a page that just redirects you to the TTS People Ops team.
If a contractor feels they will be working over 45hour cap due to an incident, application launch or overloaded sprint, they should email the Login.gov FinOps lead, team Supervisor, and team Product Owner for approval prior to going over the weekly hour cap.
Notification exceptions: if an incident occurs on a Friday or weekend, email requests can be sent by EOD the following Monday.
