Poor or shoddy work quality happens when a mechanic cuts corners to get a job done faster. The quality of the job suffers, which may cause the repair to be ineffective or fail prematurely. In the worst cases, failure of a repair may cause additional mechanical damage to the vehicle or pose a safety risk.

Poor work quality is often encouraged by a mechanic not getting paid fairly Most mechanics work under a “flat rate” system. This system does not have to be unfair to mechanics. However, in reality and common practice, managers often abuse it, causing mechanics to take a financial loss. Under flat rate, the mechanic gets paid for only a certain amount of time on a service or repair job whether they work longer than the set time or shorter. There are mechanics that prosper under the flat rate system, but this is far from the norm.
