Pros
They very occasionally provide transport to big events. Easy online sign up with no interview.
Cons
When I arrived at the five-day festival, I was told beforehand that there would be catering. After a rude introduction from the hap tent, I proceeded to set my tent up. There was no catering on day one, disappointing. Then catering on the following days were scraps! For people working long 10-hour shifts for several days, under heavy pressure, exerting themselves, people need proper, real food! Not a long-life croissant and stale sandwich in a dirty environment (the catering tent was never clean and water was dripping from the tent roof into the instant coffee). "Dinner" was abysmal - only providing a small frozen microwave meal late at night in the dark behind the bar tent. Disgusting, so I was forced to decline and go hungry yet again as they would not provide any alternative. The whole time I felt shuttled around like cattle. They assigned shift times per day then kept changing the shift times by word of mouth during the festival, so people were always confused. When I returned to the campsite on the last evening, the hap tent had already packed up and gone! Not a care in the world, didn't let anyone know, so I had no point of contact. Very bad communication from management. All in all, I would not return for any more shifts with hap solutions, don't waste your time and effort, find a better company!
