At the beginning of an employment relationship you may be reluctant to ask for changes in your contract of employment or to ask for some clarifications. Hence you may end up signing a contract with some hesitation.
If you want to put your mind at rest and discuss your concerns, advice may be given as to whether you should bring this to the forefront with your new employer. Furthermore guidance will be provided on how to approach such a sensitive matter.
It is always better to have things clear from the beginning rather than leave it to chance.
