Sometimes you may have a bad day, when stress about family, bills, friends or other pressures may cause you to harbor a negative attitude. This is normal, but it's important to remember to not allow your negative attitude to surface in a professional environment. A bad attitude can not only affect your work performance and output, it can also affect your coworkers' work days and even, perhaps, how your boss views you.
A foul attitude at work can put a damper on relations between you and your coworkers, who often -- depending on what your line of work is -- function as a team. If you have a continually negative attitude, your coworkers may see you as a pessimistic team member and, in turn, may not want to work with you. If your place of work has a more social atmosphere, your coworkers may also leave you out of social get-togethers they hold outside of work. Also, your coworkers may report to management that they find it hard to work with you professionally because of your negative attitude.
A negative attitude may prompt management to get involved, especially if management sees that work output, work ethic or interpersonal relations between work teams are strained because of a sour temperament. Your manager may take you aside and warn you that your attitude is not conducive to a team environment and that it's affecting production. If he has to take you aside more than once about your attitude, he may then have to leave an official note on your permanent work file about your behavior.
If your negative attitude persists even after your manager's warnings, you may be fired if she deems you detrimental to the work cycle. If firing is out of the question, then you might be one of the first to to be laid off if your company ever conducts lay offs, as the permanent marks on your work file would serve as a red flag to your capability as an employee.
Whether you choose to leave your place of work on your own accord or whether you are fired or laid off, if you've harbored a negative attitude that's become apparent to coworkers and management, you may have a hard time finding a good candidate to recommend you for your next job. Bad recommendations can impact what type of job you get next, and future potential employers may reassess your contribution to their business if they hear about your negative attitude.
