should i receive my vacation pay after quiting

Under the Texas Payday Act, an employer is required to pay a departing employee unused vacation and sick leave (or paid time off - PTO) only if it has a written policy that it will do so and then only under such terms and conditions as that policy provides.  If your employer has such a written policy, then the Texas Workforce Commission - Labor Law Department (800-332-9243), which enforces the Payday Act will accept your complaint and collect the unused time off pay. Best of luck
