Screwballburling, it worked for many years in an airline I worked for in Germany. They found themselves with too many Captains one winter and asked for volunteers! The deal was you had to share with another who would work alternate calender months on half the salary. I shared with another guy who lived overseas so it suited him too. When the company discovered that they could get 6 X 100 hours out of us in a year, a total of 1200 hours as opposed to 1000 from one captain, they saw the light and let us stay on the deal for years. The extra 200 hours they got out of us paid for the extra sim ride on their side and we got 6/10ths of our previous annual flight pay. It is a win-win situation if only you can get the wheels to see it that way. We also gave up our leave entitelment. 6 Months a year on furlough was quite enough!
I ran a boat business and my partner ran a holiday company in our spare time.
Overall we came out with about 60% of our previous earnings, plus what we made in our other jobs.
