Is the job market in Singapore struggling across all industries, or only in specific ones?

Asking for one of my nephews who will be taking his o levels next year. I understand that sectors like tech, finance, and services are currently facing a slowdown, with fewer job openings and more contract roles instead of permanent positions. However, I'm curious about other industries such as healthcare and the built environment (like facilities management). I heard from people working in those areas that it's actually challenging to find manpower. like to hear your thoughts especially from those in sectors where the job market is still strong
