Our household set up is such that we could survive on just the OH’s salary if absolute needs be, so no real worry that I could be out of work.
The ‘it’s not forever’ aspect of contracting suits me right now and if you suffer from itchy feet, short term contracts look better than never sticking in any one permie job for very long.
Like the above poster mentions, I find it easier to switch off from work and not let aspects get to me when I know I’m not going to be somewhere long term.
(plus I get paid a lot more :-D )
