Companies vary regarding vacation/sick leave/paid time off etc. Comparing what one company does vs another doesn't really accomplish much and you have to consider the entire context of the benefits offered. Where I work, no one encourages salary employees to come to work if ill. No one ever heard of covid prior to 2019, so the applicable HR policies were written years ago. It is rare for a salary employee to be out of work for illness, tends to be more of the exception vs the norm. Many companies with hourly employees have union agreements that describe the applicable policies. I agree with others, that a company can choose benefits MORE generous than the federal requirements, but not LESS.
As I understand the overtime rules, salary employees who spend less than 50% of their time directing others are classified as non-exempt and much be paid overtime when working. Exempt employees are classified as spending more than 50% of their time managing subordinates, are not required to be paid overtime. I believe those are the federal guidelines but don't work in HR. How much extra you get paid for overtime I don't believe is specified by the govt but each company decides that on their own.
