On-call

On-call means being available to take work outside normal hours if a call comes in. In a service company it is the technician who takes the emergency calls that week, usually on a rotation, and in DispatchLine it is also a setting: which team member gets the emergency alert, and which number the agent transfers a live emergency call to.

On-call meaning for pay: when it counts as work

For employees covered by the federal Fair Labor Standards Act, the Department of Labor’s rule on on-call time (29 CFR 785.17) draws the line by how free the person is:

• Required to stay on the employer’s premises, or so close that the time can’t be used for their own purposes: that on-call time is working time.
• Only required to leave word at home or with the company where they can be reached: that on-call time is not working time.

A tech who carries the phone at home is usually closer to the second case, but the details of your arrangement and your state’s own wage rules matter, so check them with your state labor department or an employment lawyer before you set on-call pay.

Why it matters for a service company

A shop with three trucks gives one tech the phone each week. The usual arrangement forwards the business line straight to his cell. At 9 PM he is under a sink on a paid job, the call goes to voicemail, and the caller with water spreading through the kitchen is already dialing the next shop. The other failure runs the opposite way: an answering service pages “leak, call back” with no address and no sense of urgency, and the same tech is woken at 2 AM for a drip that could have waited until morning.

A rotation only works when something sits in front of the tech and does three things. It filters what is actually urgent from what is not. It collects the address, the problem and a callback number before anyone is woken. And it has a fallback when the tech cannot pick up, so the caller is not dropped into voicemail.

How DispatchLine handles it

You choose the emergency action in the portal: book the emergency slot and alert the tech on duty, transfer the call live to the on-call number, or take the details for a callback. Handing the phone to next week’s tech is an edit to your emergency rules, without a ticket.
