As someone who's usually stuck being a workplace first aider due to being an ex nurse, but it's been a few years...
Afaik it's not advised. Not only due to allergies but because paracetamol is hugely problematic as a popular method of suicide - that's why there's restrictions on who can sell them and how many per customer.
I would NEVER have done this. Asking for trouble.

A - you can develop allergy to something you've invested a million times before with no issues - has happened to me with several meds in recent years.
B - paracetamol is contraindicated with certain conditions. People don't always pay attention when being told
C - paracetamol od either accidental or intentional is horrific. It is not a quick death but long and painful yet people still do it. Depression and other mental illnesses are not logical - there's a lot of sense in the phrase "while the balance of their mind was disturbed" people in distress don't act sensibly always.
D - there could also be problems with if there's ANY children could access at op's work (eg staff offspring, work experience), or indeed other vulnerable folk who might not know not to take easily available medication.
"I assume they pay their staff a decent wage/salary." HA! Aye right! Yea there's no issues with working people using food banks or in fuel poverty either eh?! 🙄
It SHOULDN'T be necessary as employers SHOULD age paying a living wage and the govt SHOULDN'T be leaving new employees with no money coming for the first month of employment at the very least! Meanwhile in the real world, there ARE women and girls left seriously stuck in dealing with a monthly occurrence who shouldn't be.
You and pigsDOfly would do well to read the NUMEROUS posts on threads discussing period poverty and indeed poverty in general, food bank use and the utter farce that is UC! There are women, families going without essential food and shelter let alone period products, there are on the streets homeless people working full time in well known chains! And it's not a few it's been established its well into 1000's of people probably more.
