There has definitely been an increase in people working from home in the last two years and many companies have continued with this model even after offices reopened. The benefits to businesses have been that they no longer need to rent as much office space for their employees which means the cost of heating and lighting the office has reduced and staff absences has fallen. For employees, the benefits of working from home can be seen as they will spend less time commuting, with the associated costs, and may feel happier working in familiar surroundings.
In order to be really productive when working from home it is essential that you have a dedicated workspace so that you do not feel that your work life is encroaching on your home life. Even having a desk or table in a corner of the living room will be enough if it is not possible to have an entire room to use as a home office. Adhering to set work hours can also help to define work and home time so that you do not feel that you are always at work and taking regular breaks during the day for lunch and coffee will prevent your blood sugar levels dropping mid-afternoon.
