Arizona law requires employers to have at least two pay periods per month, spaced no more than 16 days apart. Employers must pay all wages due each pay period. In other words, they can't delay payment of wages to a subsequent pay period. Most employees are entitled to overtime pay for all hours over 40 in a work week. Some employees fall into one of several overtime "exemptions," however. A lawyer would need more information about how your are paid and your job duties to determine whether you a exempt from overtime. Good luck.
