I worked for a small company with a &gt;25 person IT team once, and everyone participated in the on-call. When you were on-call, you were on-call for the entire department. I worked IT security, but I was on-call for networking, servers, code, database, and even power outages. The shifts were for two weeks straight and were non-transferrable, so we couldn&#x27;t trade off. We needed to be sober, ready to go any time of day or night, and able to be on-site at any of the locations around the city within half an hour. Even if the phone rang at 3am.<p>I quit after seven months. I wasn&#x27;t getting paid nearly enough to go through that.
