We sent the entire team last year for a 4-day training, if I am not mistaking.
I also believe that we have budgeted the same for 2015, not for this year – please double-check
Don’t worry about the guests, they are not in a position to ask for the certificates of our guys and anyway, they all have one.
In the absence of any legal text -which is still very surprising to me considering the importance of tourism in Thailand-, a one-year old certificate is good enough.
In my opinion should only attend this training whoever has a certificate 2 years-old or more, or has joined the life-guard team after last year training.
