Our company is considering a new cell phone plan. Unfortunately, we can no longer afford to pay for the entirety of employee cell phone usage, so we are adjusting our contribution to 25%. When we reviewed past employee cell phone records, we found that only around a quarter of calls were business-related, which seems fair. Because we are still paying for a portion of the phone, we still have access to all personal records on the employee's cell phone and can view this information at any point. Some employees are questioning the ethicality of this, saying it goes against their privacy rights.

If an employer pays for any portion of an employee's phone plan, should the employer have access to all records of the phone, including private text messages and voice conversations? What are the cons of this situation.
