So all of my new clients have been here for a year now, only one has been here for almost 2 years (jan). I was thinking about raising my rates by $5 a week on Jan 1, this works out to $1 a day or $.10 an hour based on a 10 hour day. I don't usually raise rates for existing clients, I have actually only done it once in 19 years. I only give the new rate to new clients and leave everyone else the same. Do you think I should write up a notice for Dec 1, saying that the new rates will be effective Jan 1?
