My 'availability' is different to the actual hours I work.
I have only recently put my foot down and organised myself as I found I was working most days (never weekends) with appointments scattered all over.
My evenings were getting taken over & I felt ever so guilty towards my son but it was too hard to say no.
I am now (aside from when it was Xmas) available for appointments:
Monday & Thursdays
8am-7pm
Tuesday, Wednesday & Friday
9-3pm
That doesn't mean I work ALL those hours... would be raking it in doing 40 hours/40 sets of nails a week
... no hands left either lol!!
If someone wants Monday, I start off offering them my first app at 8am...
If someone wants an afternoon and I already have work booked on the Monday morning I'd then book the Tuesday 2pm so i can try avoid a gap but still finish at 3 for the school run.. I then work backwards/forwards around those appointments... As best as I can anyway.
I try leave Fridays free for last minute appointments.
Obviously this doesn't always work but it's amazing how many people have now got set routine appointments since I have done this as they know otherwise they won't get in.
My evenings have been strictly Mondays and Thursdays and funnily enough, the ones who could 'only do evenings' have miraculously become available at other times since it's no long an option to have me working every evening.
