When is the right time for hiring?
It’s always difficult when starting up to know when is the right time to start hiring casual/part-time/full-time as you grow and scale.
I speak from experience myself and advising other start-ups legally. I think the approach generally to start off hiring casuals as a good way of protecting your legal position if you need to replace quickly without too many consequences.
Obviously it’s a double edged sword if they want to up and leave without giving you notice.
