My experience working short term jobs in the past is that they pay weekly but operate on a stricked pay cycle. If your hours aren't posted by a certain date/time of the week then payment for those hours gets shifted to the next pay period. Are they disputing the hours owed to you? Try to work it out on your own before going towards the legal action direction. Go in person, don't call, and speak to your rep about the hours and pay date.

Hi Virginia: Ugh, that sounds so frustrating! I would definitely get in contact with an employment lawyer to see if what they're doing is illegal. A lot of lawyers offer free consultations, so you can at least find out if you have a case. Hope this helps!
