Department of Commerce Boulder Laboratories

For Friday, April 17: The DOC Boulder Labs will have a 2-hour early departure today. Snow is present for the Boulder area. 

  • The site will close 2 hours early, and staff should leave 2 hours earlier than their normal departure time.
  • Conferences will adjourn by the early release time.

  • Designated emergency employees may be required to remain at work as scheduled.
  • Telework employees at the office will receive weather and safety leave only for the time required to commute home. Once these employees arrive at home, they must complete any remaining portion of the workday by teleworking (will not count toward the 52 hours), taking unscheduled leave (paid or unpaid) or other paid time off, or a combination.
  • Non-telework employees at the office will be dismissed no later than the final departure time and granted weather and safety leave for the number of hours remaining in their workday.
  • Telework employees performing telework are expected to continue working and generally may not receive weather and safety leave. They must account for the entire workday by teleworking, taking unscheduled leave (paid or unpaid) or other paid time off, or a combination.
  • Remote workers are expected to continue working and generally may not receive weather and safety leave. They must account for the entire workday by working, taking unscheduled leave (paid or unpaid) or other paid time off, or a combination.
  • Employees departing the office prior to their early departure time may request unscheduled leave (paid or unpaid) or other paid time off. Such employees will not be granted weather and safety leave for any part of the workday.
  • Employees on preapproved leave (paid or unpaid) or other paid time off (e.g., compensatory time off, credit hours), including an employee who has requested unscheduled leave, generally should continue to be charged leave or other paid time off during the scheduled time and should not receive weather and safety leave.
