Here is a "addendum" to a job description I found online. It sounds like a blanket excuse to totally swamp a new employee with additional and/or distasteful responsibilities that have no relevance to the actual job:
Job Description Disclaimer
This job description should not be considered all-inclusive. It is merely a guide of expected duties. The employee understands that the job description is neither complete, nor permanent and may be modified at any time. At the request of their supervisor, an employee may be asked to perform additional duties or take on additional responsibilities without notice.
Here is what I would place at the bottom of MY resume in response to such BS:
This resume should not be considered all-inclusive. It is merely a synopsis of relevant experience and duties successfully performed. The employer should understand that the resume is neither complete, nor static and may be modified at any time to fit an advertised position. If hired, the candidate may request that the employer provide regular and frequent opportunities to learn additional skills and/or assume a higher level of responsibilities commensurate with the employee's accumulated abilities.
I wonder what Liz Ryan would think!
