It’s not FOs specifically, but CA and FOs on the CRJ. Anyone bidding below 25-30% in base is being awarded lots of monthly flying.
It’s more of a massive growth pain than an attrition pain. SkyW grew by 50 pilots last month. (+100-50)

The 175 will probably experience issues next year as it is set to expand by 40-50% in 12 months.

On the CRJ side we all dodged a bullet when the 30 United 700s were placed with other carriers. Things would have come to a screeching halt. Instead of complaining about timing out, we would be complaining about being on reserve for 12 months and 4 year upgrades.
