The Laboratory observes official University holidays as listed below. These holidays are granted with pay to employees, except as otherwise stated in subsequent paragraphs below. The days listed below or announced equivalents are usually observed as holidays:
When one of the listed days occurs on a Sunday, the following Monday is observed as a holiday. When a holiday falls on a Saturday, the preceding Friday is observed as a holiday unless an alternate day is designated by the Laboratory Director.
The Laboratory will be open on both Cesar Chavez Day and Veterans Day and closed during the winter holiday shutdown. Employees electing to use the floating holiday on either Cesar Chavez Day or Veterans Day will be required to use a third vacation day or leave without pay day during the winter holiday shutdown.
The floating holiday must be taken during the calendar year and cannot be accrued
for future use.
Exempt employees do not normally receive extra compensation when their assignment requires work on a holiday.
Nonexempt employees are paid for time worked on a holiday. They normally receive a full day's holiday pay, plus pay for any portion of the day worked, to the nearest hour for monthly salaried personnel and to the nearest quarter hour for hourly rated personnel.
Nonexempt employees who are working irregular full-time schedules are entitled to the same number of paid holiday hours granted to regularly scheduled employees. An employee whose regular day off falls on a holiday observed by the Laboratory receives holiday pay.
4. Cesar Chavez Day and Veterans' Day
Nonexempt employees working on Cesar Chavez Day and Veterans' Day will be
paid for hours worked only. They will not receive additional holiday pay.
Employees who work variable time schedules do not earn holiday time off with
pay.
Part-time employees who are scheduled to work half-time or more are allowed holiday time off with pay in accordance with the following table:
| Percentage of full time | Hours of holiday pay per holiday |
| Under 50 | 0 |
| 50–56 | 4 |
| 57–68 | 5 |
| 69–81 | 6 |
| 82–93 | 7 |
| 94–100 | 8 |
A full-time employee on approved, nondisciplinary leave of absence without pay for no more than 20 calendar days is eligible to be paid for any holidays occurring during the leave period.
An employee on leave without pay for more than 20 calendar days is not eligible to be paid for any holidays that occur during or immediately before the leave period begins.
The observance of a religious holiday may be permitted by a division director or department head. In such cases, time off is charged to accumulated vacation credit. If no credit has been accumulated, the time off will be handled as leave without pay for nonexempt employees and, at the discretion of the division director or department head, for exempt employees.
A new full-time employee will be paid for any holiday immediately preceding his or her first day of work if the holiday is the first working day of a pay period. This rule does not apply to part-time employees.
A terminating full-time employee will receive pay for any holiday immediately following his or her last day of work if the holiday is the last working day of a pay period. This rule does not apply to part-time employees.
