Lots of full time guys and gals have been asking for part time for severals years but BA have refused due to the old part time contracts giving rise to large peaks and troughs in work coverage, which made crewing difficult. Also the large recruitment numbers over the last few years meant it was difficult to let people go part time as this would require even more recruitment.
The new BA/BALPA agreement allows for a new part time roster schedule that smooths out the peaks and troughs. This will allow all those who wanted the various part time options to get them and this should allow for more recruitment. So good news.
