Do you envision someone with Obsessive Compulsive Personality Disorder (OCPD) as a fast-food employee discarding dozens of hamburgers because the patty is not centered on the bun?
Their Obsessions Annoy You
People with OCPD are generally very high-functioning individuals, even though some mental health professionals may try to “fix” them and the uninformed attempt to avoid them. Because of their attention to detail, many become entrepreneurs. In fact they are, quite justifiably, ideal candidates for most employers who are privileged to find them and know how to manage their temperament.
Don’t Confuse OCD With OCPD
To allay apprehension of these special individuals, first distinguish the difference between OCPD and OCD. Those with the former will quickly recognize the omission of the “P” in the latter. As a “personality” trait, its designation relates more to a tendency to focus on extremely high standards. They are self-starters and generally do not require nagging to get a job done. Doesn’t this appeal to employers? People with OCPD are generally efficient software programmers, architects, designers, accountants, engineers, and mechanics—ones said to have type-a personalities.
Though OCD and OCPD share some symptoms of compulsion, the two disorders are only distantly related. People with Obsessive-Compulsive Disorder are often aware that their compulsions (multiple hand washings; repeatedly circling the block) are abnormal but are compelled to perform them anyway. People with Obsessive-Compulsive Personality Disorder, however, believe their need for strict order and rules is perfectly normal.  It is possible, though not common, for an individual to have both traits.
Those with OCPD generally feel their actions are quite normal and justified.
Obsessive-Compulsive Personality Disorder is characterized by a preoccupation with orderliness, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency. Individuals with this disorder usually express affection in a highly controlled or stilted fashion and may be very uncomfortable in the presence of others who are emotionally expressive. 
Nevertheless, OCPD employees do require commendation for their often over-the-top efforts. An employer might say, “Your hard work really paid off. The immediate benefit that comes to mind is how easily it will now be to maintain this list. And I’m certain you can point out many other features.” Just don’t be surprised if he diminishes commendation by showing indifference or listing personal errors.
Don’t Go “There”
Because OCPD describes a personality, and those with it generally feel their actions are quite normal and justified. It does little good to tell them they are paying “too much attention” to quality, are “too efficient,” or they make “too many lists.” This would be akin to telling a comedian he is odd because he tells too many jokes. However, someone whom they trust can interject an outside perspective when they are awkwardly transferring their obsessions.
Avoid making it sound as though he [*] is deficient, saying: “Since you apparently have OCPD, you need to just do it this way.” In fact, any criticism is best if constructive—not presented as condemnatory faults. It is better to praise his good qualities and share ways in which they are beneficial. “This is good as it is; but how much better do you think it will be if you do this…” Remember, a person with OCPD does not think he has a problem. Though behavior may strongly suggest the conclusion, medical diagnosis is best left to a professional.
Benefits of OCPD
The fact is, companies require structure, organization and lists. It is therefore prudent to assign such responsibilities to OCPD employees. This doesn’t mean they must rein absolute control over every department. But they may receive relative authority to make schedules or maintain detailed information. They can work well in accounting or human resources departments or be ideal executive assistants. Accurate job descriptions may be important since OCPD employees will vigorously strive to follow established rules.

If they question the logic of instructions, it may be that they genuinely can suggest an improvement. In a large company, policies and procedures must be properly documented, so an OCPD employee can be reminded of this while assuring him that the suggestion is noted and will be given consideration.
Relationships With Others
Those with OCPD can manifest traits of outwardly- or inwardly-focused perfectionists. IFP often prefer to work isolated where they can enforce extremely high personal standards and obsess over details. OFP tend to be concerned about how they appear to others and may expect perfection from coworkers or subordinates. Both tend to have difficulty delegating—preferring to maintain control by doing everything themselves.
People with OCPD can’t be “cured” of their personality.
In attempting to control outcomes by doing the work themselves or spending time and energy worrying about or checking the work of others, perfectionists are prone to waste time and offend others. By doing so, they inadvertently communicate that they do not trust the work of others or believe their work is not good enough. [3,4] Those who understand their trait are less offended.
