The Advantages and Disadvantages of Working from Home

The Advantages and Disadvantages of Working from Home Working from home is a dream for many but it has its pitfalls. Bayt.com highlights the advantages and disadvantages of working from home.

As more and more professionals seek a better work-life balance and more companies adopt flexible policies to accommodate shifting workplace priorities and realities the working from home option is becoming increasingly viable. Employees see this as an ideal means to remain in the workforce and continue to be employed thereby maintaining all the tangible benefits of being part of an established company, while enjoying all the advantages of being based at home. The option has its potential pitfalls however and below we discuss some of the advantages and disadvantages of working from home.

Advantages

By working at home you save on many hidden costs associated with going to work. These include costs of commuting, car wear and tear, fuel, road taxes, parking as well as indirect costs such as expensive professional wardrobes and the dry-cleaning of those. Often you can also save on older children’s care arrangements although for younger children it is highly unadvisable to forgo the childcare arrangement and try to balance close care and supervision with the demands of the job.

This doesn’t just relate to timings either although the flexibility to determine your own work hours to some extent is the most important aspect of this. You can also determine your environment, lighting, temperature, setting, mood; basically work in the framework that suits you best and makes you happiest and most productive.

Coworkers banter and distractions, unnecessary interruptions, unimportant meetings can all be avoided if you are safely at home and sealed off in your own environment which you have barricaded from any possible interruptions.

Proximity to home and family

For many, the physical proximity to family and the convenience of being at home are tremendously comforting. For parents it can be especially pacifying to know that they are very near to their children and available should they be needed for any reason. This also applies in the case of elderly care.

The stress of commuting in bumper-to-bumper traffic at rush hour in many countries is extremely counterproductive and can lead to disgruntled workers who are already exhausted and worn before they have even begun their day. This is especially true where the workplace is far from the office. Other stresses often cited include unfriendly coworkers, a suboptimal work environment and constant distractions.

Removed from the stresses and distractions of the workplace and working independently in their own preferred environment at their own pace, professionals are often a lot happier and a lot more productive.

Often with long commutes and anywhere from 1 to 3 hours a day spent getting to and from the workplace both physical and mental health are adversely impacted; the former as the gym hours are usually the first to go and the latter due to the stresses associated with both the commute and the workplace itself. By working at home the commuting time saved enables you to resume physical exercise, to go for a long walk for example before and after work or to join a local gym.

Better work/life balance

Work/life balance, the aspiration of the modern professional, is often achieved and tuned to satisfaction through a working at home arrangement, particularly when a professional has the flexibility to report into the office and work from the office partially as an option and can fine-tune the arrangement to achieve the most optimal balance.

Disadvantages

Often, professionals working from home complain of isolation and loneliness given their removal from their bosses and coworkers and th is can be very depressing to some. Since the workplace provides a location to meet people and make friends for many, professionals working from home have to be more creative and resourceful in getting to know people and in staying in touch with their colleagues.

Although office distractions are avoided by working at home, different distractions may arise. Interruptions from children, work, neighbours, friends, family may be very disruptive and special efforts must be made to make it known that you are actually working and unavailable for interruption within work hours despite your physical presence at home.

Difficulty in separating home from work

The temptation to engage in household matters since you are at home is often very strong. Suddenly you may start feeling obliged to clean the home, do the shopping, the childcare, the cooking, the home finances and the socializing all while meeting the full requirements of the job too. It is essential to draw the line between home and work so as to avoid both areas suffering.

Work doesn’t end

Since there is no-one looking over your shoulder enforcing strict hours you may feel tempted to work endlessly. This pressure to work endlessly may be compounded by the fact that you feel there are greater expectations made of you as a home-worker or by self-imposed pressures to prove yourself and your abilities in this arrangement. Moreover the lack of physical separation between home and work may add to this pressure to work endlessly.

Alienated from daily company developments

A lot can change from day to day in a company and you may find yourself removed from important developments such as staff changes, new business, changes in company direction, new competitive intelligence etc.

Danger of being overlooked for promotion

The danger of being overlooked for promotions and career development opportunities is quite real when you are away from the office and other more visible employees are actively and aggressively vying for them. An open line of communication with management and regular visits to the office are critical in order to prove your dedication and commitment to your career and to prevent the out-of-sight-out-of-mind syndrome.

Need for high self-discipline

Working from home is not for anyone. It takes a lot of dedication, self-control and discipline to motivate yourself to persevere in working at home alone over the long run without succumbing to the distractions and losing drive and momentum. Often a partial arrangement where you report into the office once or twice a week is the optimal arrangement as it allows for close interaction with colleagues and supervisors and ensures you remain in touch with company developments while still permitting you the comfort and convenience of working from home.

1. Dirk Strauss A lot of the concerns about working from home are valid ones. Personally I feel that most of these are easily overcome. The most important consideration is to separate your home environment from your work environment. I wrote an article on working from home for anyone considering telecommuting.

Wed 02-Apr-2014 17:03 PM - Report Inappropriate Comment 4. Najat Nasser All above applies when staff is working 100% from home. Sometimes working from home is an option available in for staff only when related with some other conditions (light sickness/child care/etc.). this provides staff with flexibility to help performing in a relaxed environment, reduces stress and increases productivity and loyalty. this elimiates many disadvantages listed in the reading.

The biggest constraint ( provided if you are a dedicated professional) is that it becomes very difficult to get yourself out of the office domain/mindset even after working hours.

Nivedita Timlapur Given the present day situation, working from home is indeed a best option because 1. of peak traffic adding up to the travel time 2. houses are not available closer to your work place or they are too expensive, which forces people to travel long distances.

Urban Dictionary: work@home

Government service jargon and employee shorthand for defrauding taxpayers. Used as a noun, and certainly never as a verb, it describes a state-of-being generally accompanied by euphoria and giddiness from stealing from the “man.” Except, in this case, it is not the “man”, it is the people. The state-of-being derives from sweet contracting side gigs while sitting at home on the government dime, saving both on childcare and gasoline for your new sweet SUV that you only have drive to “work” two days a week.

Although the state-of-being is generally continuous, it is sometimes interrupted by home chores, trips to Sam’s Club, meetings with side gig clients, and lines at Starbucks. The state-of-being is highly contagious among peers, and newcomers are taught to be giant assholes by the veterans until the impotent management says “fuck it, I’d rather these turds stay at home in bliss than interrupt my web surfing, and if I am the only one at work, it makes me look important.”

“I get so much more done when I work@home.”

How do I Work at Home? (with pictures) - mobile wiseGEEK

wiseGEEK: How do I Work at Home?

The idea of working at home was once restricted to artisans and artists; those who could handcraft a product, write, paint, or sculpt. Such is no longer the case. Due to enhanced technology and the ever-increasing presence of the internet, work at home jobs now exist in abundance. If you are considering working at home, however, there are a number of factors that should be taken into consideration. You must possess a marketable talent, self-discipline, the right tools, and the ability to function without close supervision or feedback.

First, working at home is not a good choice for those who either desire or require a high degree of social interaction. In most cases you will be working alone, and must avoid the temptation to put off until tomorrow what must be done today. It is a good choice for those who seek part-time work or a bit of extra income. It is true than many individuals do choose to work at home as a full-time career, but following this course requires extreme dedication, the ability to multi-task, and a strong desire for personal freedom.

If you have an attitude suitable to successfully working at home, then you would be wise to invest in a landline phone, up-to-date computer, and a high-speed internet link. You should also set up a specific workspace in your home, and keep it free of clutter and non-work related items. Working at home is best accomplished if you continue to function as if you were going to a regular nine-to-five job. You are now wearing the hats of employer, supervisor, and employee, and need to set certain rules and guidelines.

Some people find it helpful to begin work at the same time each day, while others are capable of altering their hours as circumstances dictate. It is also good to set up a daily “to-do” list of tasks that must be accomplished before your workday ends. You should take periodic breaks, just as you would at a traditional job. Take a lunch hour and make sure to leave the house a few times each day, even if just for 10 or 15 minutes. This will prevent burnout, and will aid greatly in keeping your focus on the tasks at hand.

Working at home should be approached in very similar manner to working in an office. If you are telecommuting for a large firm, or are on a salary. you will have pre-defined jobs and a relatively low stress level. If you are a work at home freelancer. the opposite is true. If you fall into the latter category, you should be constantly looking for new opportunities, as it is not unusual for the work at home freelancer to serve as an independent contractor for a half dozen or more companies.

This means that you will need to keep track of billing, invoices, and expenses. Often it may seem that there are simply not enough hours in the day, but it is critical that you take the time to clean the house, walk the dog, spend time with your family, and get plenty of sleep. Remember that you made this leap to enhance your life. When the workday is done, simple close your office door and take part in those activities you enjoy.

Article Discussion

3) I am a people person, and I would be totally out of sorts trying to work at home. I love my family and home, but work allows me to get a needed break from both.

2) The company I work for started a work at home program a couple of years ago that allowed some of its workers to work one day a week at home. Much of our work is dealing with paperwork, so most of it can be done at home anyway if you have a computer and phone.

The idea behind the new program was that it would save the worker and the company money. The company would save money because there would be fewer people using electricity, paper, water and whatever things we employees use that costs the company money.

We the employees saved by not having to commute to work and not having to go out and buy lunch. The best part for me was getting to sleep in late and not being in a stressful setting.

Unfortunately, this program ended after a few months because many of the workers were not getting as much work done on the days they worked from home. And I was one of those workers not getting as much done. When I worked from home, it would always be around noon before I sat down to get to work, and by then it was almost lunchtime, and I couldn't catch up.

1) I could not agree more with what this article says in the final paragraph about a freelancer who works from home needing to be sure to take time to do other activities not related to work. I am a freelance worker, and I used to work more and more hours in an attempt to do more work and make more money. I have since learned that the two do not necessarily go hand-in-hand.

I found that the more I worked the less productive I became. After so many hours a day and so many days in a row I need a break. I learned that I get more done when I take weekends off and have fun instead of trying to get in another day or two of work.

Sure I get more done when I work seven days, but then the following week I am usually burned out by Wednesday, and I accomplish way less than I should. In general, a well defined and steady pace wins the race.
