There is nothing wrong with wanting to work a little less. Hairdressers give so much of themselves each day I think that each stylists should find whatever work/ life balance they choose.
For many years, I was a 6 day a week stylist. Eventually after our academies opened and we had 3 salon locations, I cut back to 2 days a week. And each time I reduced my hours, I raised my prices. Demand was far exceeding my available hours, and I was charging a lot of money, though eventually I had to stop doing hair altogether.
You can get paid like you’re working full-time but while spending less time in the salon. But you can’t just cut back unless you’ve set yourself up for success.
