I worked many jobs here in US and they all had holiday pay. So if I worked I would get paid 1.5x and if I didn't work I would still get paid as if I did.
Not supporting the idea that anyone is entitled to this, but saying it is not uncommon. I think it is regional within the US and maybe depends if you are hourly or salary based.
If you get paid time-off, then that is paid at your normal rate of pay, and you don't have to work for it.
If you work one day during your PTO, then surely that work should be compensated at your daily rate of pay, in addition to your pay for time-off. Why should you work a day at half-pay?
So working during paid time-off should be compensated at double-time.
Time-and-a-half was customary in the UK for overtime, in the days of trades unions. The opportunity to work overtime was prized, and in fact sometimes workers would "go slow" during normal time, to ensure there was enough work left for overtime. Nobody worked normal hours that included public holidays, so those hours were compensated at double time. Christmas Day would sometimes command triple-time.
It depends on how deep the employer's pockets are and what supply and demand looks like for the type of labor. Fast food workers, small retail businesses, franchised hotels, all do not typically get holiday pay. Generally, the lower the income, the lower the chance of holiday pay.
