I'm an OTJ emergency/ICU tech in the Washington, DC area and make $14.10/hr. I'm in the home stretch to complete my skill sign-offs that will let me earn a raise to about $17/hr. Cost of living is very high here - my tiny studio apartment costs me $865/month in rent.
Benefits are good where I work - good health and dental insurance for about $150/month, 3 weeks of annual leave per year that begins accruing after 6 months, excellent discount on vet care for personal pets, up to $1500 every other year toward CE for non-credentialed techs and every year for credentialed techs, holiday pay, hospital provided uniforms, credit union membership, subsidized gym membership, and other stuff I'm forgetting right now. I really have it pretty good where I am.
Before I went there, I was an OTJ tech at a small day practice (1 full time and 3 part time DVMs, fewer than 10 support staff) where I earned $11/hr plus HMO health benefits for $150/month, 1 week of paid leave a year, a $50 uniform allowance at the beginning of employment, holiday pay, and a discount on vet care for personal pets. This was not my first vet job - I came in with emergency, ward, general practice, and spay/neuter clinic experience.
Pay and benefits vary widely even in the same geographic area. The good thing is that once you have some skills under your belt you have some leverage to gain better pay and benefits for yourself.
