Office perks are tax efficient. They aren’t subject to payroll taxes and are a deductible business expense. Not having any perks at all would be wasteful.
Also notable - there are companies that provide 'free' perks for your staff where a few of them are concrete and the rest are discounts on things from their marketing partners.
Honestly, I'd be tempted to sign up and then tell incoming employees the truth thereof.
That's great for investors, but the benefit to employees is minimal. No, free snacks don't count as a benefit lol.
