I had to be off work for a few weeks for a surgery last year, and the only thing I could really do was find another reputable nail tech to refer them to. I contacted the other nail tech first, to ask her permission first off and also let her know my situation and offer the same to her. Turns out, she visits family for a month every year and was greatful to have someone to take care of HER clients when SHE'S gone. So now we trade. And if you're worried about losing clients because the other tech is better, well then you've got to step up your game eh? Good motivation lol. But I will be honest in saying that most of my clients just decided to wait it out, whether they came back with none left or not. At least your clients have an option and someone you have recommended.
