Managers may view the teleworker as experiencing a drop in productivity during the first few months. This drop occurs as "the employee, his peers, and the manager adjust to the new work regimen". The drop could also be due to inadequate office setup. Additionally, a 1999 study claimed that "70 minutes of each day in a regular office are wasted by interruptions, yakking around the photocopier, and other distractions". Over the long term, though, surveys found that productivity of the teleworker will climb; over two-thirds of employers report increased productivity among telecommuters, according to a 2008 survey. Traditional line managers are accustomed to managing by observation and not necessarily by results. This causes a serious obstacle in organizations attempting to adopt telecommuting. Liability and workers' compensation can become serious issues as well. Weaker relationships between job dimensions and job outcomes, such as job performance and absenteeism, may explain why the results regarding performance and telework are conflicting. Some studies have found that telework increases productivity in workers and leads to higher supervisor ratings of performance and higher performance appraisals. However, another study found that professional isolation in teleworkers led to a decrease in job performance, especially for those who spent more time teleworking and engaged in fewer face-to-face interactions. Thus, similar to job attitudes, the amount of time spent teleworking may also influence the relationship between telework and job performance.
Writing copy for websites is another great freelancing option for those who have a way with words. Copywriting can involve writing the text for websites, press releases, promotional offline materials including leaflets and brochures, and any other professional text for businesses. While writing blog posts is well paid it won’t make you as much money as writing copy for sales pages. However, clients can be more fussy, as they want the highest quality writing for the forefront of their website or advertising campaigns. Many freelance writers offer both copywriting and blog writing amongst their services. This can be a good way to juggle regular but lower paid clients (blogging) with the higher paid but ad-hoc project based copy work.
How to Get It: Customer service is the biggest work-at-home field, with companies including Spiegel, Hilton, Best Western, HSN, 1-800-FLOWERS and many others using at-home reps. Fill out an application with staffing companies such as Arise, Alpine Access, VIPdesk, LiveOps, and Convergys, all of which vet the companies who are hiring through them. If you need benefits, search through a staffing company that will hire you as an employee (Alpine Access, VIPdesk and Convergys do this) rather than an independent contractor. If you're a contractor, you may be asked to pay a small fee (between $15 and $35) for a background check. While a fee can be a sign of a scam, independent contractors are responsible for their own expenses.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt).

It’s an excellent opportunity to offer technical training courses that teach people how to learn a much-needed skill, or accomplish an important task.

If you have a good idea for an app, and the skills to create it, then producing your own premium app can be profitable. However, with so many free apps available, it may be hard to convince people to pay. If you want to go down the premium app route, consider having a basic free version to encourage people to download the app in the first place. You can then provide the option of upgrading to a premium plan once users realize how useful the app is.

Holly told me she started writing content in 2011. At the time, she still worked a full-time job but created content online part-time to supplement her income.
