This first one isn't really a work from home perk but it's a perk. My boss is great and understanding. My coworkers are funny and help the day go on. And yes, I have coworkers. I'm on a team and we can talk in a chat room. We have one room for business stuff and another where we can talk about anything - and we do when it's not busy.
One of the biggest work from home perks for me, is I can work in my pj's. And I do. With all my health issues being comfortable while I work is really great. I can also work in the dark and there are no bright fluorescent lights. This really helps a lot with my migraines.
After my seizures happened last month, I was told that I wouldn't be able to drive for three months. If I worked outside the home, I'd be screwed since Todd works 2nd shift. But since I work from home, it's business as usual. I did ease myself back in, thank again to a great boss, but I've been back full time for a couple of weeks now.
Working home works great for me. It seems like more and more people are going that route as well. As someone who has chronic pain, it really helps me be able to be comfortable, be able to crash into bed after my shift if needed but still make a living to help my family.
