My fiance got fired cause it wasn't working out. Can his boss fire him for that reason?

Generally an employer can terminate you at any time, without even having to provide a reason why, as long as it is done on a 'without cause' basis and the employee is paid out his or her termination and/or severance entitlements. Your fiance should contact our office to schedule a consult with one of our employment lawyers so we can further review his matter and assess his termination entitlements.
