had hours taking off the schedule with no explanation after working 40 hours a week for over a year. will not tell me why.

If I understand your question, the employer has reduced the number of hours it is scheduling you to work each week.  Unless you have a contract, you are most likely an at-will employee.  Under the at-will employment doctrine in Texas, you or your employer may end your employment at any time with or without a reason (but not an illegal reason such as race, sex, age, religion, disability etc.) and with or without notice.  Implield within that doctrine is a right for the employer to promote you, demote you, increase or decrease your pay and adjust your hours of work. Without a written agreement, an employer has no obligation to guarantee you 40 hours of work per week, even if it has done so in the past. Good luck.
