I would dread to be in a company with a bidding system that is based solely on seniority. The outfit I work for has a rotating bid system which seems to be a more popular way of doing things when speaking to those that have experienced both methods. I chatted to a friend who works for a company who has a seniority based bidding system and they recently spent their first Christmas at home for a few years whilst I have had three out of the four past Christmas Days at home and I more of less wrote my own roster for last December. I am only half of the way up the seniority list on my fleet as well in the RHS.
