I'm the only IT person for a business with 130 users and 10 locations plus a second business with 25 employees and one location. I'm responsible for everything - desktops/laptop support, phones and blackberry, routers, servers (file shares, exchange, DCs, sql, citrix, term server, etc), and purchasing. I'm also on-call. Honestly, some days I'm overwhelmed and others are quiet. I have an IT consulting group on retainer for when I need advise or an extra person for a day. I also have a very supportive non-IT manager.
