Thank you, I work for the the Department of corrections in a clerical position, my co-workers want a 4day 10 hr shift, are we entitled to a paid lunch break? Can we work the straight 10 with out one or is it against the labor code.[/SIZE]

Regarding meal periods, see here:

Alternative workweeks such as the one you want must be approved by the state Labor Commissioner. See section 511 of the Labor Code here:
