There is a thing, a tool, that a lot of folks use, it is called "insurance" every team pays say $100 per worker per month to the FIA, the FIA buys a policy for maternity, as it is not going to happen every month, and if a staff member happens to need leave, it is paid from the insurance, really this is a solved problem.. Re-insurers would love to cover this as it is for them profit, you have income and compound interest accrue on this account, then once in a while, you withdraw, really why this is an issue speaks to the lack of adults in F1, sorry but F1/Liberty/FIA lack the adult in the room...This is such a non issue, so what if it costs $1m per bun, how many buns are going to be in the oven in a given season? The fines from going 0.1 kph over the limit would pay for at least 1 year of premiums for 1 member, all the fines, really.. Can the F1 industry start investing in the hiring of sane rational adults??
Do teams like Red Bull, Mercedes and Ferrari could end up paying as much as £300k a month to the FIA for a complicated insurance policy. Sounds like a really great idea for saving costs.
Or they could just use the existing method for maternity leave which costs them a fraction of the cost and applies to all companies in the country.
