Almost every one I know is sick, or is working/living with someone who is sick. There are some nasty bugs out there getting hold of people and refusing to let go. Most people, a few days after antibiotics and rest start to feel better and slowly get back to their routines. Many also think a great way to really push the feel better effect is to get their nails done, hair done, a massage etc. My theory---you can never be too safe when it comes to the spread of germs.
Businesses can't shut down due to sickness and you can't do anything about sick clients coming in. Maintaining a clean environment is always a top priority, during the "sick" months it is vital!
Stocking up on your regular disinfectant to spray your implements and work stations is a good way to ensure germs don't have a chance! Also, keeping bottles of hand sanitizer on work stations, bathrooms, waiting areas...anywhere a client can see it will also help (think safety in numbers!!!) People may not think about carrying it or even using it, however if it is in their line of sight they are more likely to take advantage of it.
Don't let germs this season take over your business! Prevention is key!
