When they made me drive a bus that was leaking exhaust. I kept asking for a new bus. But drove for 9 hrs with flumes coming thru the vents. And another time drove a bus. With gas fumes. I have the courtesy cards the passenger's filled out. Complaints of fumes. To this day i use a inhaler. Some of their buses are being held together by bandaids. Attached pic showes passenger's complaints. I put in complaints. So i think thats why they laid me off .I should of sued them . I have constant lung problems. And i dont smoke .
