As the popularity of worker rentals grows, we often find ourselves short of SCCA members for key work positions.
The result is that typically someone needs to volunteer to fill these key positions, thus negating the real "convenience" of worker rentals.
Needless to say, worker rentals make Worker Chief's job even more difficult, as trying to scrap together a worker group with insufficient number of SCCA members isn't fun...

Also, the quality of course work I've personally seen has been pretty subpar and typical of the most novice workers.
Maybe is it due to a lack of understanding about the rules of the sport? Lack of caring? Exhaustion (if some workers are doing course work all day, perhaps)?
Maybe limiting only 5 rental workers per heat would be a good start?
I certainly think it needs to be discussed....
