They work the crap out of those guys. Yours may limp in and out but many work 12 hour days easy. Remember, they don't punch a clock so they are expected to be there early and stay late. Weekend conf calls are also very common. Many have to remote in to the system from their home computers to check on reports and such as well. Mine comes in on outbound frequently after being there all day and heads in most weekends. A guy in a small end of line would have it easier but the bigger facilities the job is way beyond full time. It is like owning your own business without any of the benefits.
