1) The cost of recruitment is an additional pressure to have your employees work long hours. Finding/hiring a 10x'er is hard. If I push my 10x'ers to work full time and yours are working half-time, you need to hire twice as many to match my productivity. 2) On the flip-side, it's interesting to consider if 4 part-timers are more valuable than 2 full-timers. You get twice the brain cells and you'd get more "work-time spillover" (people working/thinking their off-hours). This might be especially true in a smaller company where you often can't afford to hire enough full-timers to get a lot of diverse thinking. I can't tell you how many startups I meet could benefit from a second designer but aren't even close to being able to afford one. Of course, higher headcount means higher communication overhead, too.
