I passed my one year anniversary at Market. There are plenty of pros: nice people, trusting management, friendly, helpful people in the shop, paid on time, the trailers tandems all slide without a battle, nice Volvo trucks w/ automatic transmissions. Healthcare thru Kaiser is a very much appreciated option.
However, like with any company, there are some annoying bits: the "getting to pop in at home" thing has become a rarity; DMs are under a lot of pressure to run their drivers >9000 miles/month which can be difficult to attain. Simply put, life gets in the way of their 9000 mile goal, and I rarely hit it. That means that my pay is lower, because you get a 3 cent per mile bonus when you exceed 9000 miles. On the other hand, a good work/life balance is very important to me. So after one year, I am staying on, at least for now.
