If you look after your employees financially and give them quality of life you won’t have that problem.
when employees leave, it’s just business. They have families to support and will do what is in their best interest so look after them and they won’t leave.
If you can’t afford to or won’t then you should not have gone into business.
Just like when times are tough for companies during economic downturns they will cut employees loose in the blink of an eye regardless of their mortgage, kids school fees, food for their family etc and their motto is it’s nothing personal..,Just business, well it works both ways.
