Do we need to cancel our volunteer visa and work permits before leaving Thailand?

The user inquired about the necessity of canceling their volunteer multi-entry visa and work permits before leaving Thailand for a year. The comments suggest that if they are on a yearly visa extension requiring 90-day reporting, they should cancel it; however, if on a multi-entry visa with border crossings every 90 days, they may not need to cancel anything. It is strongly advised to cancel the work permit at the Ministry of Labour.
