It's legal in Texas for an employer to do just about anything. In Texas you can be fired without cause. For sure there is no law requiring an employer to allow overtime. The employer can hire extra and /or temporary help to work the extra hours or have salaried non hourly employees work them, or even reclassify employees almost at will. The only requirements an employer might have to follow would be in an employment contract that covered the things the laws or lack of them don't address. Texas is a "right to work" state and has taken it to the extreme of being a "right to screw employees" state. The Texas Employment Commission has been privatized and is now known as the Texas Workforce Commission, its primary goals are now not to find employment for citizens but to find cheap labor for business, lower workmen's comp payments in amount and time, lower unemployment payments in amount and time,find loopholes so employers can opt out of workmen's comp and unemployment insurance, lower employer liabilities for negligence, and all kinds of stuff like that , even providing legal advice to employers who don't want to pay overtime. Making a wild guess, do you happen to work for a Big Box? Wal-Mart? Home Depot?
