One thing I have never quite understood is why company's are so worried about large leave balances, and more so during COVID.
Hasn't anyone taken a class in accounting? The expense is recognised when the work is done, not when the leave is taken. The fact that a company has $x in leave liability means nothing, because they also have $x on the asset side of the balance sheet in cash that would have to be paid if employees took all their leave today.
The only time I can see it making a difference is if an employee gets a raise. Say they go from $50k to $60k, that means the value of the leave has increased by 20%. But other than that, there is no difference. Or its that increase that they all worry about? If that is the case, why don't they build into contracts that leave balances translate into an equivalent $ amount on job changes?
Part of it is that extra cost after a raise (and you can't contact it, from what I understand, that's against the law), but part of it is the health of the employee. A burnt out employee reduces their effectiveness.
