This could be an excellent job, but it's ruined be terrible management and a culture of 'play it by ear to get through today'. If a van breaks down or someone phones in, just split all the deliveries on to others even if it makes every customers delivery late. No back up plan, ever. The more you do the more you get with no thanks. Some guys don't have to work weekends or back shift ever, while others are forced to work every weekend and lots of nights. You risk your life on the road, take responsibility for a 40 grand van, drive in terrible conditions, walk 100 miles a day, lift up to 4 tons a day, get soaked, frozen, climb a thousand stairs every shift, put up with angry customers, go into stinking houses, get petty rules rammed down your throat, no weekends off, constantly bombarded with texts to take overtime at standard pay rate at the last minute and all for the same money as the guy in the air conditioned phone shop texting his pals all day in the same shop.
If you need a short term job, take it but keep looking and don't believe any promise or fairy story they tell you at the start, there is a reason why they are constantly looking for more drivers.
Money, conditions, incompetent management.
