Many beginning or inexperienced cashiers earn the federal minimum wage ($7.25 per hour as of July, 24, 2009), but many states set minimum wages higher than the federal minimum. Cashiers' work hours vary by employer, and sometimes require them to work during weekends and holidays. Some cashiers employed in establishments that operate 24 hours a day, such as gasoline stations, work overnight shifts. Part-time work is common.
Conditional mood often refers to an inflected verb form, like the example just given. However the term is also sometimes used in relation to an analytic construction that performs the same function. Thus a construction like the English would love will sometimes be described as representing the conditional mood.
The verb of the main clause is in the future tense with  will  (or sometimes another modal). The verb of the conditional clause is in the simple present tense. Occasionally, the open conditional statement describes one potential state of reality or circumstance which is dependent on another.
