During the pandemic, hotel rooms rapidly escalated in prices. I travel often for work, and I noticed a huge different in cost. The rooms are also cleaned less often and there are fewer staff in the hotels. So yes, they need raises, hotel staff are hard working people that historically have been underpaid.
I noticed Vegas was not on the strike list. I suspect it's because they make pretty good money in Vegas working in hotels. Ironically it's union or the fear of unions that keeps the wages high. One hotel that was proud to be non-union said they would compare local contracts, tax the highest wage and add 20% as long as the staff did not attempt to unionize. Either way the union helped them get better pay and treatment.
