A no call, no show is an absence from the workforce without notifying the employer. This form of absence is generally deemed inconsiderate and unprofessional. When workers miss work, especially in jobs where one's workload would require to be substituted for the day (teachers, cashiers, servers, etc.), it is generally expected that they call in advance to inform of his or her absence so that their workload can be completed by the present workers. Many businesses have forms of punishments as a result of no call, no shows such as counseling statements, suspension, and possibly termination of employment.
There are numerous reasons that a no call, no show occurs:
Sometimes, employees who do not show up to work without reporting are quitting the job and by doing so abandon their position and discontinue all further communications with the employer.
There are times, however, when a no call, no show is not preventable, such as when an employee is suffering a medical emergency and is unable to communicate with the employer. An employer is more likely to excuse such an absence if the employee has a good prior attendance record or supplies satisfactory documentation of the unexpected nature of the situation (such as paperwork from an ambulance or hospital).
In some cases, the employee does report the absence to the employer (such as by leaving a message), but the employer fails to receive the communication.
It can also be mistaken that the employee simply wants to take the day off (despite the risk of any disciplinary action that might occur in this situation) and does not want to deal with any possible hassling questions from the employer, as made famous by the character Peter Gibbons in the film Office Space ("I think I'm just going to ... not go.")
In retail positions, there are often scheduling inconsistencies in which employees think that they are working a different shift that day (or for that matter, working an entirely different day) instead of the one scheduled. Some employers consider this a form of no call, no show.
