It would be a lot more straightforward for the company to sever the services of the less experienced (say those with CL26s, in order to be ready to enact a second genesis of the SG workforce, when the time comes. This will guarantee an uninterruptible path forward, for the company to transition this temporary “glitch” without much business and operational impact.
If the attrition is reversed and top-side biased, it would be an almost impossible task to regenerate ourselves with a bunch of half-baked, low/no-experience employees, who had likely stayed on, only to eye at the SLS and DH positions vacated, that they think they would like, but have no capability at all, to fill!
