While at work employees are expected to exercise the same discretion in using personal cellular phones as is expected for the use of company phones. A reasonable standard the company encourages is to limit personal calls during work time to no more than one per day as needed for a duration of a few minutes only. Employees are therefore asked to make any other personal calls on non-work time where possible and to ensure that friends and family members are aware of the company's policy.
Employees whose job responsibilities do not specifically include driving as an essential function, but who are issued a cell phone for business use, are also expected to abide by the provisions above. Under no circumstances are employees allowed to place themselves at risk to fulfill business needs.
