Thanks Simon for chiming in with a positive and real experience. We have a work-force of over 50 men right now - I invite readers to come to the jobsite to see diligent, hardworking men doing heavy lifting in the heat all day long. And many ask for more hours, even taking on extra tasks on Sundays.
Some caveats - they won't work if they are disrespected, and they do want to be happy/enjoy when on the job. The crew is proud of what they do, and they don't tolerate slackers. When you come to the site you will hear a lot of laughter and music and will encounter people worthy of enormous respect.
Are attitudes and customs different than in North America - for sure. If you don't understand these customs and realities well enough to hire the right individuals and if you don't have innate management skills, you may indeed end up with less than fabulous employees.
