The most common type where the employee spends most of his/her time working in the office and WFH is something they do only occasionally. Employees are given laptops, cell phones, and access to the corporate network to enable them to perform work and attend meetings outside of business hours.
Occasional work from home during business hours. Some companies allow their employees to WFH one day/week as a routine practice (NB: the best day for that is Wednesday). The employee typically has some sort of designated workspace in the home, although it often isn’t a full home office (perhaps just a desk in a guest room).
Most common with sales, consulting, and field service roles where primary job responsibilities are outside the company’s offices at a customer site. It doesn’t require the workspace assigned in the company offices. For those teleworkers that WFH primarily, they often have a dedicated “home office” space (a separate room in the home) that is equipped with all of the office furniture, supplies, and resources that one might find in a company office building.
These are the entire business functions that work from home full time. IT systems, business processes, and management practices are optimized for a distributed workforce. Meetings take place via conferencing systems instead of in conference rooms. Documents are shared electronically instead of printed. Workflows are enabled via IT systems instead of physical interaction.
Some companies are entirely virtual with no physical office at all, or maybe just a small space for company leaders to meet. Other companies leverage a virtual workforce setup for functions like customer service (answering phones and emails). In contrast, other functions like product development, finance, and administration work in traditional office settings.
