<prompt> Human: My employer has rolled out a new mandate stating that we must work a full half hour before time is added to our payroll.For example:Steve is scheduled to work from 0600 to 1400. He is contractually obligated to hold until he is relived from his post. His relief arrives and relives him at 1420. His week end hours amount to 40:20. He is paid for 40.Is this a legal amount an employer can withhold pay?If not, please include links to state and it federal statutes so that I legaly hold my ground and educate myself on the matter.Thank you.Edit: Thank you all! Everything you guys have said had just reaffirmed my suppositions. Ill be updating should this go from bad to worse!  <response>: time to join a union
