Johns Hopkins University School of Medicine

When conditions require curtailment of the operating schedule of the university or a particular unit, the change will be announced on the university weather hotline and website (see box below).
Information on a closure or delayed opening is made available as soon as a decision is made, normally before 6 a.m. after overnight snowfall.
  Staff members may be designated as required-attendance  employees. Expectations for school of medicine requiredattendance
employees who work in clinical areas may be explicitly aligned
with Johns Hopkins Hospital inclement weather policies and guidelines.
 
Required Attendance Plan
An on-site, required-attendance employee must stay at work or report to work. This employee is one who is vital to the operation of a work group and whose presence and critical services are required regardless of the emergency.
  Required-attendance employees who do not stay at or report to work may be considered absent without approval, pending discussion with their supervisor.
  An off-site, required-attendance employee is one who may best be utilized during an emergency by working from an alternate off-site location: either the employee’s home or elsewhere.
  Each unit or department defines its staffing requirements. Supervisors should annually and in writing designate required-attendance employees of either type. If your status is unclear, discuss it with your supervisor.
  A third category is the nonrequired attendance
employee who is asked to work. At the discretion of a unit or department, employees not previously designated for required attendance may be called to work on a case-by-case basis. They may be required to report to work, work from home or report to a designated alternate worksite during the emergency. When possible,
employees should be given advance notice that they might be called into service.
 
Closure Plan
The Johns Hopkins University may choose to close the entire university, a campus or a building. Required-attendance employees in the affected area must remain at work or report for work
at the regularly scheduled time, either on-site or off-site as previously designated. Nonrequired-attendance employees do not work unless asked to do so.
 
Delayed Arrival Plan
When the delayed arrival plan is invoked for the entire university, a campus or a building, all required-attendance employees are to report to work at the regularly scheduled start time, either on-site or offsite
as previously designated. Other staff members are expected to report to work by the delayed arrival time. Employees reporting by that time will not lose pay or have time charged to leave.
