Though many employers would like to get rid of their "problem employees", some employers are reluctant to fire those who one would expect would be deserving of termination. There are many reasons for this, which may include: Some positions may be hard to fill. This may be the case with a rare skilled position, or with certain low-wage jobs that are generally unattractive, where finding applicants is difficult. A person who has unusual skills, or who is doing a job that is considered undesirable, such as cleaning sewage from pipes, may be hard to replace. As such, a person in this position may be retained even if they have absenteeism or conduct problems.
