Although some employers will be comfortable sending everyone home with their laptop and saying, go forth and be productive, most will want to be a little more specific. A good telecommuting policy will generally address productivity standards, hours of work, how and when employees should be in contact with their manager or subordinates, and office expenses.
For instance, your policy might require that employees are available by phone and messaging app during their regular in-office hours, that they meet all deadlines and maintain client contacts per usual, and that they check in with their manager at the close of each workday to report what they have accomplished. Be sure to let employees know whom to contact if they run into technical difficulties at home.
You’ll also want to specify how expenses related to working from home will be dealt with. If you don’t expect there to be any additional expenses involved, communicate this. You don’t want employees thinking this is their chance to purchase a standing desk and fancy ergonomic chair on your dime. That said, you should consider whether employees will incur reasonable and necessary expenses while working from home. Some states mandate reimbursement for these kinds of expenses, but it’s a good practice to cover such costs even if it’s not required by law.
