speaking from personal, and recent, experience. training bonds are not worth the paper there're written on!!!
if a company wants to bond you they are admitting they are not providing the conditions and pay to make you stay of your own accord. so they force you to stay.
If a company says 'we need you to do a job on a particular aircraft' then the decision is on them to provide you with the appropriate training to conduct the job they require of you. the days of feeling guilty from receiving an aircraft rating are over.
if an accountant received training to operate a new computer system would there be a training bond... i think not.
i'm working for a company who is changing fleet type. it wasn't my decision to change, if they want to get a new type then they need to provide the training!!
some of you newbies need to know your worth!!!
nuff sed!
