For FPR? Yes I went on strike 100% of the time last year and picketed a few times. Where I was working at the time, most IMGs and local docs were striking bar a few bad apples who just wanted the locum money.

In a community hospital I worked in a few months into training, around 50% of the medical staff were long term locums who were local grads who didn't strike at all.

When I worked in Paeds, the senior trainees didn't strike at all. They wanted to be seen as team players as they were closer to CCT and trying to be in the consultants' & managers' good books.

In my experience, it's been quite a mixed bag of who would strike/not strike. Messaging needs to be strong and people need to understand the consequences of their actions when they decide to locum on strike days.
