PR holders in Singapore can apply for any job they want, and they can freely change companies, industries, and careers whenever they want to. Compared to those with employment passes or work permits only, PR holders do not need to change visas while doing all of these. Foreigners who are not permanent residents must continuously follow the conditions of their work visas and change them if needed.
For example, if you are a holder of a work-related Singapore visa
and want to switch to another job, you must cancel your old Singapore visa and reapply for a new one. You should also note that this does not ensure approval. Despite your previous work permit, your application is still subject to delay if further clarification is needed, or rejection if you do not fulfil the prerequisites. This is the main difference between a permanent resident holder and a work permit or employment pass holder.
