Wow, I can't begin to see how you're drawing parallels between a research staff and a boat & dive crew. How do they do their work faster? Cut time off our dive? Rinse BC's and regs faster? I'd prefer they give proper time to maintaining that life supporting equipment and I'm happy to tip them for not rushing the experiences I find so enjoyable.
And where does this "fixed monthly wage" come from? Should operators increase the cost per dive to $100 or $200 per cylinder? Or should there be tax on dicers, or tourists in general, managed by the government?
Either way, the money comes out of your pocket. Doesn't it?
This is tourism. People work hard to create a good experience. Show your gratitude with kind words, repeat business and a lousy $20 (if not more) at the end of the dive.
I perfectly understand how the tipping culture works. Simply I do not like it...
The monthly wage should come from the tour operator.
When I was working as a DM I was an employee of a tour operator called Club Vacanze.
Customers did purchase holiday packages advertised as "all included": air travel, transfer to the resort, lodging, meals, wine and water, snimation, all kind of sports, included scuba diving (max 2 dives per day).
It was a great commercial success.
As customers did not pay for each dive, there was no pressure to have them "diving more". The pressure was to keep them happy. And the first step for having happy customers is to have an happy staff.
So we had a great working environment, well paid and with rewards for good employees.
Customers had to fill up an evaluation questionnaire at end of their vacation, and good members of staff, reveiving appreciation, were rewarded by the tour operator.
Rewards were in some case a day free of work ("you are a customer today"), in some others diving equipment (the tour operator had an agreement with Cressi, so we had a lot of give-away material for customers, which was often given also to the staff as a reward for good service).
Customers had that nice experience of travelling without money in their pockets, as in these resorts everything was already included. No surprises, no extra cost...
There was even a free medical consultancy, with a resident hyperbaric doctor as a member of the staff. At Maldives we had in our island a two-compartment hyperbaric chamber, and the staff did include the hyperbaric doctor, two hyperbaric technicians, one marine biologist and one astrophysic. The latter was managing a 400mm telescope, used for watching stars and planets.
After working 5 years in such a professional and well managed workplace, I do not really understand how other crap tour operators can stay in business, providing lower service, with unpaid DMs who rely on tips for surviving.
Our diving industry should be reformed, aligning to the best tour operators.
