I work in the natural resource industry that has a huge labour shortage at the moment so I'm always getting messages from recruiters. It's annoying though because I don't think they actually understand what type of position they're trying to recruit for. My understanding is that the commissions on our (high) salaries are enough that if the recruiter even places only a few people then they've made a year's salary, especially given the low overhead, so there's no incentive to actually do the job properly. It all smacks of get rich quick scheme. As such, it's hard to take them seriously when they get in touch. My former employer even went so far as so stipulate on their website that they would only deal with contracted recruiting firms.
Today I was just referred for an ultrasound to check out a breast lump. I am freaking the fuck out because a) I'm a hypochondriac, but also b) I just quit my job (with insurance) here in the States to take another one in the UK. Luckily my worst case scenario involves moving back to Canada (where I'm originally from), and being taken care of by my parents and government health care once I clear the three month "I'm moving back" period.
